### Full prompt
```text
Using the reference photo as a subject reference, create a close-up portrait blending high-end illustrative realism with delicate ink linework and soft watercolor washes. Depict the face with smooth porcelain skin texture, subtle blush, and expressive, sparkling eyes. Flowing strands of hair and edges of fabric dissolve into abstract, transparent shards of color and paint splatters. The background is crisp white negative space overlaid with faint architectural outlines, geometric construction grids, and technical drawing elements. Rendered in a soft pastel palette of [soft blues, warm yellows, pale pinks, and light grays] with controlled saturation, balancing precise sketch lines with loose, atmospheric fashion editorial illustration.
