Professional studio product photography of [product from uploaded photo], placed on a glossy reflective black-blue mirror surface with a clear, crisp reflection beneath it. Monochromatic deep cobalt / ultramarine blue background, seamless and saturated. A large, soft-edged dark shadow of a human hand with long, spidery, slightly bent fingers is cast on the back wall above the product, reaching down toward it, creating a mysterious, eerie, Halloween-inspired mood. The product is in sharp focus, centered in the lower third of the frame, preserving its exact shape, colors, label, typography, and branding from the uploaded photo. Low-key lighting: soft cool blue ambient light, a subtle rim light outlining the product edges, gentle highlights on the packaging, deep moody shadows. Minimalist composition, lots of negative space above, cinematic and editorial feel, high-end skincare / cosmetics advertising aesthetic. Shot on a medium-format camera, 85mm lens, f/5.6, ultra-detailed, photorealistic, 8K, vertical 3:4 aspect ratio.
