Lively ink-and-wash book illustration on warm white textured watercolor paper. Use a fine, quick black pen line with lightly overlapping contours, open edges and charming hand-drawn irregularities. Add loose transparent watercolor washes that occasionally drift beyond the drawing. Keep generous untouched paper and a few tiny pigment splashes. Use coral pink, peony rose, lavender, mint, pale turquoise and restrained apricot-orange accents. Preserve clear silhouettes and expressive observational details. Handmade, airy and vivid, never slick or digitally airbrushed.
