Spring Cherry Blossom Girl Collage

Create a high-end vertical fashion collage poster in the dreamy Japanese-Korean watercolor illustration style. 
Centered in composition, the protagonist is a beautiful anime-style college girl with a full-body portrait of a soft, elegant aesthetic. Her long black curls have a hint of purple-green highlight, she wears an oversized sweater dress printed with cherry blossom patterns, layered fashion accessories, wears transparent glasses on her head and platform sneakers, her posture relaxed and elegant, cheeks slightly flushed, eyes bright, and delicate ink sketch lines. 
The characters are surrounded by planner collage elements: tear-like paper, vintage notebook pages, tape-attached Polaroid frames, close-ups of cherry blossoms, butterfly stickers, city park scenery, beautiful close-ups of eyes, handwritten words on paper, and blooming cherry blossom branches. 
Soft spring atmosphere, light green + blush + cream tones, watercolor splashes, ink grading effects, hand-drawn graffiti embellishments, magazine editorial layout, luxurious fashionable niche magazine aesthetics, Japanese stationery style, layered paper-cutting composition, soft cinematic lighting, light background blur, dreamy feminine atmosphere, and exquisite details.
