Transform only the people in the uploaded photograph into adorable hand-drawn doodle characters while keeping the entire original photographic background unchanged.

FORMAT LOCK
Vertical 3:4 composition. Preserve the original framing, camera angle, perspective, lighting, colors, and scene structure.

BACKGROUND LOCK - CRITICAL
Keep the original sky, landscape, buildings, water, furniture, ground, plants, railings, objects, lighting, colors, perspective, textures, and environmental details fully photographic. Do not redraw, simplify, stylize, illustrate, or apply doodle effects to anything except the people.

PEOPLE TRANSFORMATION
Replace each person with a charming naive doodle character while preserving the exact number of people, original position, relative scale, orientation, head direction, body direction, pose, gestures, arm and leg positions, interactions, hairstyle, clothing colors, and major accessories. If a person faces away, keep them back-facing. If sideways, keep them sideways. If facing forward, keep them forward-facing. Never rotate a person toward the camera or invent facial features that are not visible.

DOODLE STYLE
Adorable imperfect hand-drawn characters with oversized round heads, tiny compact bodies, short simplified limbs, tiny hands and feet, cute awkward proportions, loose scribbled hair, tiny dot eyes and simple facial features only when visible, and subtle rosy scribbled cheeks when appropriate.

DRAWING TECHNIQUE
Loose naive children's-sketch aesthetic. Thin shaky black outlines, imperfect shapes, overlapping sketch lines, scribbled colored-pencil or crayon fills, uneven coloring, small white gaps, rough edges, and intentionally handmade imperfections. Keep the characters simple, charming, expressive, and slightly exaggerated.

INTEGRATION
Maintain accurate scale, ground contact, depth, perspective, lighting interaction, and natural occlusion. Doodle characters should occupy exactly the same locations as the original people and interact naturally with photographic objects. Objects being held or touched remain fully photographic.

COMPOSITION PRIORITY
Original photographic background
Exact person position and scale
Original body orientation
Original pose and gestures
Cute exaggerated doodle character design

FINAL LOOK
The image should feel like the real people were replaced with adorable hand-drawn doodle versions while the real-world photograph remained untouched. Create a convincing mixed-media contrast between realistic photography and handmade doodle characters.

NEGATIVE PROMPT
Avoid full-image illustration, background doodling, stylized scenery, realistic anatomy, anime, manga, 3D cartoon, polished digital art, vector lines, changed poses, changed orientation, invented faces, added people, altered background, altered objects, altered lighting, or unwanted environmental effects.

Based on the uploaded reference photo, directly create a 3:4 vertical travel souvenir postcard in the style of “real photograph × quirky crayon memory illustration.” First understand the content and visual story of the photo, then generate the final artwork directly. Do not output any explanation, analysis, or additional prompt text.

OVERALL COMPOSITION

Use a strict 3:4 vertical composition divided horizontally into two equal sections, with the top 50% and bottom 50% exactly the same height. The two sections should feel naturally connected while maintaining a clear contrast between a real photographic moment and a hand-drawn memory of that moment.

TOP 50% — REAL PHOTOGRAPH

Keep the uploaded photograph as the primary visual source. Preserve the original subjects, number of people or animals, identity, pose, body proportions, facial expressions, clothing, objects, spatial relationships, perspective, composition, and realistic photographic texture.

Preserve the original natural lighting, shadows, atmosphere, and environmental details as much as possible. Only apply subtle editorial color grading to make the photograph feel warm, refined, and slightly nostalgic.

If the image needs to be adapted to the 3:4 format, use only natural cropping or a seamless extension of existing environmental edges such as sky, ground, walls, water, roads, or vegetation. Never stretch, mirror, duplicate, redesign, or alter the original subjects.

BOTTOM 50% — QUIRKY CRAYON MEMORY ILLUSTRATION

Transform the visual memory of the photograph into a simple horizontal hand-drawn illustration rather than applying a full-photo-to-illustration filter.

Extract 2–5 of the most recognizable and memorable elements from the original photo and rearrange them into a clean, centered, horizontal mini-scene. For people or animals, preserve their recognizable pose, silhouette, proportions, and key facial characteristics.

Remove complicated distant backgrounds, tiny textures, repetitive structures, realistic photographic shadows, and irrelevant clutter. The illustration should feel like someone came home from a trip and redrew the scene from memory with crayons.

Use a warm ivory, cream, or off-white handmade paper background with subtle paper fibers, grain, and a slightly vintage printed texture.

HAND-DRAWN STYLE

The illustration should look naive, relaxed, slightly clumsy, warm, and handmade, as if carefully drawn by someone with good taste using crayons and colored pencils, but without trying to make the drawing technically perfect.

Use crayon as the main medium, supported by colored-pencil details. Lines should be dark gray, gray-brown, or soft black, with uneven thickness, slight trembling, occasional breaks, small overlaps, imperfect angles, and visible hand-drawn inaccuracies.

Use rough crayon grain, hand hatching, uneven color filling, layered strokes, slight color overflow, and areas where the paper texture naturally shows through. Even simple geometric objects should retain a subtle handmade imperfection.

The visual language should feel like retro children's picture books × independent magazine illustration × personal travel journal.

COLOR

Extract 2–4 representative colors directly from the uploaded photograph and use them as the main crayon colors.

Keep the colors soft and slightly muted, but still clearly visible and lively. Do not make the illustration pale, gray, washed out, or lifeless. Preserve the most memorable color from the original photograph so the illustration still feels visually connected to the real photo.

OVERALL FEEL

The top half represents the real moment.
The bottom half represents the memory of that moment.

The final image should feel warm, healing, relaxed, nostalgic, handmade, slightly retro, collectible, and editorial, with the quiet charm of an independent lifestyle magazine.

Cute but not cutesy. Naive but not childish. Simple but not cheap. Premium but not overly polished.

STRICTLY AVOID

Do not change, replace, beautify, or redesign the original subjects. Do not add any person, animal, vehicle, building, plant, prop, decoration, or environmental element that does not exist in the original photograph.

Do not use realistic watercolor, detailed watercolor painting, ultra-light pastel colors, washed-out colors, gray low-saturation colors, realistic pencil sketches, clean vector illustrations, anime, manga, chibi, stickers, commercial cartoon styles, oil painting, thick digital painting, digital gradients, 3D rendering, plastic textures, or overly polished digital artwork.

Do not add tape, pins, torn-paper edges, postage-stamp borders, color blocks, decorative frames, complex collage elements, location labels, dates, numbers, archive layouts, logos, watermarks, platform UI, play buttons, subtitles, or black borders.

Generate only the final image. Do not output explanations, analysis, prompt text, or any other written response.
