Summer Anime Collage Poster

Create a vertical fashion anime illustration poster of {argument name="character name" default="a young woman"} posing dynamically in the center, kneeling with one leg folded under her and the other knee raised, torso twisting, one arm stretched high above her head with fingers forming a playful gesture and the other arm crossing in front of her face. Her face should be intentionally obscured as a soft rectangular blur with no facial features. She has messy black hair tied in a loose bun with stray strands, warm light skin, a white cropped athletic tank top with black trim, black earbud cords hanging around her neck, high-waisted distressed denim short shorts with frayed hems, white scrunched socks, and chunky retro running sneakers in gray, white, teal, and small orange accents. Use crisp manga line art with realistic anatomy, clean cel shading, subtle skin texture, and a stylish contemporary editorial feel. The background is an abstract summer collage on a white canvas: include exactly 12 distinct graphic elements behind and around the figure: 1 tall cobalt-blue vertical rectangle with sky texture and speckles at upper left, 1 small white sun/moon dot inside it, 1 tiny black palm-tree silhouette cluster on the far left, 1 teal ocean photo panel with a white sailboat behind the torso, 1 black-and-white grunge vertical rectangle behind the raised arm, 1 large black-and-blue half-circle at upper right, 1 pale gray outlined rectangle behind the right arm, 1 pale cyan palm-shadow photo square at mid right, 1 pale aqua semicircle at lower left, 1 small turquoise beach-house photo rectangle at lower right, 1 narrow orange vertical accent rectangle at lower left, and 1 collection of small black and blue circular dots scattered mainly on the right. Add halftone dot patterns, black ink splatter textures, thin geometric lines, and layered rectangular cutout shapes for a mixed-media magazine-cover composition. Color palette: white, black, cobalt blue, teal, aqua, denim blue, and small orange accents. Add a tiny handwritten signature and date text in the bottom-right corner reading {argument name="date text" default="June 25, 2026"}. Keep the image clean, high-resolution, no watermark, no extra characters, no readable text except the date/signature.
