Anime Summer Soda Ad Poster

Prompt

A bright, high-energy anime-style summer advertisement poster for a sparkling soft drink, set at the seaside under a vivid cobalt-blue sky with towering white cumulus clouds and a blazing sun near the top center creating lens flare and radiant beams. Feature exactly 3 Japanese high school girls in matching summer sailor uniforms: short-sleeved white blouses with navy ribbon bows and dark navy pleated skirts. All three have dark, windblown shoulder-length to long hair and youthful, lively poses. In the left foreground, show one girl from a dramatic low angle thrusting a large plastic soda bottle toward the viewer so it dominates the composition; her hand and the bottle are oversized by perspective. In the middle, show a second girl seated low near the water, one knee raised, drinking from a smaller bottle. On the right, show a third girl standing in profile or three-quarter view, also sipping from a bottle while her hair and skirt stream in the sea breeze. Make the ocean water intensely turquoise and sunlit, with energetic splashes framing the bottom left and bottom right edges, scattered droplets and sparkling highlights across the scene. Add a few small white seabirds in the distant sky. The overall mood is refreshing, nostalgic, youthful, and cinematic, like a premium Japanese beverage commercial key visual. The bottle label should be clean and minimalist white with modern sans-serif typography reading {argument name="brand name" default="ASCII SPARK"}, with smaller flavor text {argument name="flavor text" default="Yuzu White Peach Soda"} and a subtle 500 mL marking. Place the brand logo in the upper left in thin uppercase letters, and add a handwritten-style Japanese tagline in white at the lower left reading {argument name="tagline text" default="夏がくれる、はじけるひととき。"}. Use crisp cel-shaded anime rendering mixed with painterly light effects, ultra-detailed water droplets on the bottle, condensation, transparent plastic, glittering carbonation bubbles, and dramatic foreshortening.
