Goal: Create a bright anime event banner … | AI 灵感图库

Goal: Create a bright anime event banner for an AI hand-sign challenge, featuring five illustrated girls demonstrating different hand gestures, with bold Japanese promotional typography and difficulty cards. Canvas: Wide horizontal banner, 16:9 aspect ratio, approximately 1200×675. Use a luminous fantasy greenhouse or glass atrium background with soft blue-white daylight, bokeh sparkles, pastel lens flare, and a polished social-media campaign look. Main headline: At the top center, place a large colorful title reading {argument name="headline text" default="#AI ハンドサイン チャレンジ"}. Use thick rounded Japanese display lettering with a pink-to-purple-to-blue gradient, white outline, drop shadow, small star sparkles, and a simple blue line-art waving hand icon near the title. Under it, add a small blue-pink ribbon label reading {argument name="subtitle text" default="あなたの推しハンドサインを見せてください！"}. Characters: Show exactly 5 anime-style young women arranged shoulder-to-waist across the middle, overlapping slightly, all with detailed glossy illustration quality and expressive hand poses. From left to right: 1) a black-haired fox-ear girl in a deep red off-shoulder kimono-like outfit, holding one hand thoughtfully near her chin; 2) a short blonde bob-haired girl in a white camisole and translucent pale jacket, posing with a peace sign; 3) a black-haired girl in the center wearing a black top and beige cardigan, touching one cheek with one hand; 4) a long blonde-haired girl in a white blouse reaching toward the viewer with a clear pointing gesture; 5) a lavender-blue braided-hair maid or gothic lolita girl in a black-and-white dress and frilled headband, forming a heart shape with both hands. The face area may be softly obscured or left less detailed, but the hands must be anatomically clear and central. Bottom difficulty cards: Along the bottom, create exactly 5 rounded rectangular cards with thin colored borders, soft pastel fills, small sparkle decorations, and simple line-art hand icons. The cards must read, from left to right: 1) "Lv.2" and "ピースサイン" with a peace-sign hand icon; 2) "Lv.3" and "頬に手を添える" with a cheek-touching hand icon; 3) "Lv.6" and "指差し" with a pointing-hand icon; 4) "Lv.7" and "手でハート" with two hands making a heart icon; 5) "Lv.9" and "顎の前で手を組む" with clasped hands under chin icon. Make the level numbers large and color-coded: red/orange for Lv.2, orange for Lv.3, blue for Lv.6, purple-pink for Lv.7, and violet for Lv.9. Visual style: High-quality modern anime key visual, soft painterly rendering, saturated but airy pastel colors, glossy hair highlights, clean typography, cute challenge-poster energy, sparkles throughout, crisp foreground against a dreamy blurred background. Constraints: Keep the exact count of 5 characters and 5 bottom cards. Emphasize readable Japanese text and accurate hand gestures. Avoid extra logos, dates, watermarks, or unrelated text.
