动漫风“Nice Day”海报

Goal: Create a bright vertical anime social-media poster celebrating {argument name="date text" default="July 13"} as {argument name="event name" default="Nice Day!"}, with a cheerful schoolgirl encouraging viewers to find good things and make memories.

Canvas: Vertical 3:4 illustration, high-resolution, colorful Japanese anime style. Sunny seaside promenade background with vivid blue sky, fluffy clouds, sparkling lens flare, ocean railing, greenery, sunflowers, and a festive summer atmosphere.

Main subject: One cute teenage anime girl centered slightly right, close-up upper body. She has {argument name="hair color" default="deep navy blue hair fading to cyan at the tips"}, long windblown hair, bright aqua-blue eyes, soft blush, and an open happy smile. She wears a navy sailor school uniform with white collar stripes, a large red ribbon bow, gold buttons, and a small star hair accessory near her right temple. Her left hand reaches toward the viewer in a strong foreshortened thumbs-up gesture, and her right hand holds a small spiral notebook.

Layout and text: Use playful handwritten Japanese pop typography with thick white outlines, pastel gradients, doodle stars, hearts, sparkles, and sticker-like ribbons. At the top left, large headline text reads 「7月13日」 and 「ナイスの日！」 with a pink heart. Below it, two ribbon captions read 「素敵なことを探そう♪」 and 「いい思い出を作る日」. Place a rounded speech bubble on the left saying 「ナイス〜！ 今日も最高の思い出つくろう！」. On the right, add a wooden signboard with the message 「ナイス！って言葉は、自分も相手もハッピーになれる魔法なんだよ♪」. At the bottom, large friendly text reads 「いいこといっぱい見つけて、今日を宝物にしようね！♡」.

Notebook details: The notebook held on the right is titled 「今日のナイス探し！」 and contains exactly 6 checked checklist items: 1) 「青空がナイス！」 2) 「アイスがナイス！」 3) 「友達の笑顔がナイス！」 4) 「ひまわりがナイス！」 5) 「きょみがいるのがナイス！」 6) 「ぜーんぶ、ナイス！」. Add a small line at the bottom: 「ミナミのナイス100点満点♪」.

Social overlay and photo collage: Add a livestream-style overlay in the lower left with exactly 2 UI elements: a red rounded rectangle labeled “LIVE” and a black viewer-count pill with an eye icon and “7,131”. In the lower right, create exactly 3 Polaroid-style photo cards: one turquoise cream soda by the sea, one group selfie of three girls, and one sunflower photo. Include small handwritten captions and doodled hearts around them.

Visual style: Extremely polished anime illustration, glossy eyes, soft cel shading blended with painterly highlights, saturated summer colors, sparkling highlights, cute idol-poster energy, dynamic perspective from the pointing hand, cheerful and encouraging mood.

Constraints: Keep the design busy but readable, preserve the exact Japanese text where specified, do not add extra checklist items or extra photo cards, avoid photorealism, avoid logos or watermarks.
