3:4 Vertical Split Poster: Seaside Dusk and Wave-Chasing Girl

### 3:4 Vertical Split Poster: Seaside Dusk and Wave-Chasing Girl [Core Composition and Specifications] - Canvas ratio: Vertical 3:4 poster - Layout split: Exact 50:50 horizontal division, no borders, lines, frames, or boundary marks. - Visual style: Top is realistic film photography, bottom is light transparent fairy-tale pencil watercolor, creating an upper-lower contrast. --- [Top half: Original Photograph] - Scene and subject: Golden sunset beach, a girl in a white linen dress running barefoot towards the waves, hair blown by sea breeze. Sea surface glistens, sky has warm peach and light purple sunset. - Detail reproduction: Preserve the light running motion, dress wrinkles, beach reflection, and natural sunset lighting; magazine-grade color grading. No cropping or stretching; naturally extend shoreline and sky if needed. --- [Bottom half: Pencil and Transparent Watercolor Illustration] - Form simplification: Minimal capture of running silhouette and flowing hair; omit complex wave foam and extra clutter; suggest coastline curve with a few relaxed strokes. - Pencil lines: Fine, slightly rough gray pencil strokes, light uneven pressure; skirt hem lines fade and break, contours unclosed. - Transparent watercolor: Very light sunset orange-pink and lake blue wash over skirt hem and wet ground, showing transparent wet marks and color edges. - White space: Large blank paper in front of the girl; dress interior merges with white background; colors fade before contour lines. --- [White Space and Layout] - Size and placement: Illustration is small, occupying only 20%-25% of bottom half width, positioned center-right, leaving broad sky negative space on left. - Background texture: Clean white paper with faint cotton-linen texture, no yellowing or stains. --- [Text Element] - Extracted text: 'Where the wind begins' - Typography: Typewriter light gray small font, slight ink unevenness, placed subtly in bottom-left white space of illustration. --- [Negative Prompt] - Avoid heavy shadows, thick paint, bold black outlines, digital gradient filters, cartoon stickers, advertisement layouts, and multi-image collage.
