Realism-to-Flat Style Spectrum: Illustration Reconstruction from a Single Reference Image

Using a single realistic-style portrait as the sole reference image, redraw it with qwen-image-3.0-pro/image-to-image into a flat art illustration, landing at a midpoint on the style spectrum from realism to flatness. The creative intent is to test how the model, while preserving the original figure's structure, pose, and core identifying details, distills photographic lighting and skin texture into large color blocks, simplified contours, and decorative geometric shapes; the prompt explicitly requires keeping the composition and figure traits and changing only the pictorial language, thereby distinguishing "style transfer" from "redrawing." Applicable scenarios include editorial illustration, illustration-style reworking of brand visuals, style unification for social media graphics, and batch content production that needs to retain the source image's semantics while switching visual language. The reference image is genuinely generated by the production pipeline and then fed into the author's pipeline; starting at 1K/1:1 makes rapid side-by-side comparison and iteration easy.
