3:4 Seaside Dusk Wave-Chasing Girl Split Poster AI Image Prompt

3:4 vertical split poster: seaside dusk and wave-chasing girl [Core Composition and Specs] - Canvas ratio: vertical 3:4 poster - Layout split: image divided precisely 50:50 top and bottom, with no border, edge line, frame, or divider bar. - Visual style: upper half is documentary film-style photography; lower half is light, airy, fairy-tale-style pencil watercolor, creating a quiet top-bottom echo. [Upper Half: Original Photo] - Scene and subject: on a beach lit by golden sunset, a girl in a white linen dress runs barefoot toward the waves, her long hair blown loose by the sea breeze. The sea surface glimmers with rippling light; the sky has gentle peach pink and light purple sunset clouds. - Detail restoration: fully preserve the girl's light running motion, long dress folds, beach reflection, and natural sunset lighting; magazine film-level fine color grading. Do not crop or stretch the subject; when the ratio is insufficient, naturally extend the tide and sky. [Lower Half: Pencil and Translucent Watercolor Illustration] - Form simplification: minimally capture the girl's running silhouette and flowing long hair, omit complex wave foam and extra clutter, and use only a few gentle strokes to suggest the coastline curve. - Pencil lines: thin, slightly rough gray pencil outlines, light and uneven pressure; lines at the skirt hem blur and break, contours not closed. - Transparent watercolor: very light sunset orange-pink and lake-blue watercolor gently brush across the skirt corner and wet ground beneath the feet, showing translucent moist water marks and pigment-edge blooms. - White space treatment: keep a large area of pure white paper with no brush or ink in front of the girl; large white space inside the dress merges with the white paper background. Color naturally fades before approaching the contour lines. [White Space and Layout] - Size and placement: the illustration as a whole is small, occupying only 20%~25% of the lower half's width, placed slightly toward the lower right of the image, leaving broad sky-like white space on the left. - Background material: clean white paper with slight fine cotton-linen paper texture, no yellowing, no dirt or noise. [Text Element] - Extracted copy: 风吹来的方向 (Where the wind begins) - Typography form: typewriter light gray, very small font size, with a slight intermittent ink feel, quietly placed in the white space at the lower left of the illustration. [Negative Prompt] - Avoid heavy shadows, thick paint, thick black outlines, computer gradient filters, cartoon stickers, advertising layout, and multi-image collage.
