Vertical 3:4 commercial graphic design poster for watermelon. A [creamy yellow] background features low-contrast light orange sunburst patterns and scattered light green melon seeds. In the bottom right corner, a whole oval Qilin watermelon, a half-cut watermelon, and two watermelon slices display dark green stripes, thin rinds, bright red pulp, glistening juice droplets, and black seeds. In the top left, playful bold hand-drawn typography reads '[Qilin Watermelon]' with pulp-red fill, cream inner lines, and dark green outlines, subtly incorporating a melon seed into the letterforms; below it, a wavy green ribbon displays '[Red Pulp, Juicy, Sweet and Refreshing]' alongside curved small text 'QILIN WATERMELON'. Background accents include melon field ridge lines, curling vines, yellow melon flowers, and halftone dots, with enlarged foreground leaves framing the edges. High-saturation Q-version vector illustration, retro screen printing texture, crisp flat color layering.
