Watercolor Trench Coat Fashion Illustration

Create a high-fashion watercolor and ink illustration on an off-white textured paper background, centered full-body portrait of a stylish woman walking confidently from left to right. She has hair color shoulder-length wavy bob hair and an intentionally soft, blurred, featureless face. Outfit: a long camel trench coat with wide lapels, belt straps and cuffs, worn open over a black turtleneck and loose black cropped trousers, paired with glossy black ankle boots with block heels. Accessories: one black quilted chain-strap designer handbag with a small gold clasp worn on her left shoulder, and one smartphone held in her right hand. Pose: mid-stride, left foot forward, upright fashion-model posture, coat hem and belt ends slightly swinging. Style: elegant editorial fashion sketch, fine black ink outlines, loose watercolor shading, realistic proportions, subtle highlights, minimal ground sketch under the feet. Add abstract watercolor splashes behind the figure in warm beige, ochre, rust orange, gray, and black, with scattered small paint droplets around the upper body and sides. Keep the composition airy with lots of blank paper space, no text, no border, no watermark.
