Anime Hand Sign Challenge Event Banner

Anime event promotional banner for a social media campaign, wide 16:9 horizontal format. Setting & Background: A luminous fantasy glass atrium greenhouse filled with soft blue-white natural daylight, glowing bokeh sparkles, and subtle pastel lens flares against a dreamy blurred backdrop. Typography & Headline: - Top center: A large, colorful Japanese headline reading "[#AI ハンドサイン チャレンジ]" in thick rounded display lettering with a pink-to-purple-to-blue gradient, clean white outline, subtle drop shadow, tiny star sparkles, and a minimalist blue line-art waving hand icon beside it. - Beneath headline: A small pastel ribbon label with Japanese text reading "[あなたの推しハンドサインを見せてください！]". Characters: Five distinct anime-style young women shown from waist-up across the center, slightly overlapping, featuring clear and anatomically precise hand poses: 1. (Far left): A black-haired fox-eared girl in a deep red off-shoulder kimono robe, resting one hand pensively near her chin. 2. (Left-center): A girl with a short blonde bob in a white camisole and translucent sheer jacket, flashing a two-finger peace sign. 3. (Center): A black-haired girl in a sleek black top and beige knit cardigan, gently resting one hand against her cheek. 4. (Right-center): A girl with long blonde hair in an elegant white blouse, pointing forward toward the viewer. 5. (Far right): A maid or gothic lolita girl with lavender-blue braided hair, wearing a ruffled black-and-white dress and frilled headband, forming a heart gesture with both hands. Bottom Cards: Exactly five rounded rectangular pastel cards along the bottom edge, each featuring thin colored borders, sparkles, and a simple line-art hand icon: - Card 1 (red/orange): "Lv.2" and "ピースサイン" with a peace sign icon. - Card 2 (orange): "Lv.3" and "頬に手を添える" with a hand-on-cheek icon. - Card 3 (blue): "Lv.6" and "指差し" with a pointing finger icon. - Card 4 (purple-pink): "Lv.7" and "手でハート" with a two-hand heart icon. - Card 5 (violet): "Lv.9" and "顎の前で手を組む" with clasped hands under chin icon.
