Japanese Creator Branding Poster Composition

Goal: Create a bold personal branding poster for a Japanese web creator and indie developer, mixing editorial street photography with modern startup typography. Canvas: Square 1:1 poster, high resolution, clean white background with a sunlit urban rooftop photo occupying the right and lower half. Use strong contrast, crisp details, and a premium tech brand aesthetic. Main subject: A stylish young Japanese man, {argument name="character name" default="Rita"}, seated casually on a rooftop or outdoor ledge in bright daylight. He has messy black medium length hair, black sunglasses, a relaxed confident smile, a black bomber jacket, black shirt with a vivid blue graphic accent, black pants, silver necklace, bracelet, and rings. Pose him leaning back with one knee forward and one hand resting near the foreground, looking upward to the right. Background includes a blurred modern city skyline and blue sky. Layout: Large Japanese headline on the upper left in thick black condensed sans serif type, stacked vertically in three bold lines with dramatic scale. Keep the subject on the right, partially overlapping the typography area. Add thin electric blue diagonal lines across the composition for motion and structure. Add a large blue geometric semicircle/arc block in the lower left behind the name. Add a huge handwritten electric blue signature sweeping across the lower right foreground. Text content: Use exactly 6 text groups. 1) Main headline in Japanese: {argument name="headline text" default="最短距離で、つくる。"}. 2) Small Japanese subheadline below it: {argument name="subheadline text" default="完璧主義じゃなくて、完了主義。"}. 3) Small Japanese tagline: {argument name="tagline text" default="速く出して、磨いていく。"}. 4) English tagline beneath in blue uppercase: “FAST IDEAS, REAL BUILD.” 5) Name block in the lower left: large white serif “Rita”, smaller “/ リタ”, and role line “Web制作者｜個人開発者”. 6) Contact lines at the bottom left: “@RitaStella1128” and “ritastella.com”. Visual style: Japanese startup poster design, high fashion street portrait, editorial magazine layout, bold black typography, electric blue accent color, white negative space, subtle beige halftone or ASCII text texture behind the subject and headline, sharp sunlight, cinematic realism, clean modern graphic design. Constraints: Keep all Japanese text legible and correctly placed, no extra text, no watermark, no logo other than the signature style “Rita”, maintain a polished square social media poster composition.
