Baner promocyjny zespołu rockowego anime

High-energy Japanese promotional web banner styled as an anime idol rock concert poster, in a 2:1 wide horizontal aspect ratio. Typography: Upper third features large, bold Japanese headline text in thick glossy white lettering with a heavy black drop shadow: "[ChatGPTによる画像生成が\n大幅アップデート!]". Centered directly below in smaller bold white text with a black outline: "[GPT-Image-2が無料で使える]". Typography is oversized, crisp, legible, and dominant. Characters & Layout: Arranged left to right across the bottom half are exactly 5 anime-style band members: 1. Far left: Blue-haired keyboardist with long blue hair and white blouse behind a synthesizer, face masked with a soft rectangular blur. 2. Left of center: Pink twin-tailed idol singer in a frilly pink dress with flower hair accessories, singing into a microphone with a bright, fully visible smiling face. 3. Center: Golden-yellow-haired drummer/front idol in a yellow cropped jacket and star accessories, smiling widely with drumsticks raised in front of a drum set, fully visible face. 4. Right of center: Dark green-haired bassist in a black-and-green stage outfit holding a bass guitar, face masked with a soft rectangular blur. 5. Far right: Black-haired guitarist in a gothic black-and-purple strap outfit holding an electric purple guitar, face masked with a soft rectangular blur. Background & Setting: A festive concert stage with a glowing abstract swirl knot logo centered behind the idols, encircled by a brilliant golden circular halo. Flanking the stage are futuristic display panels: neon control interface rings on the left screen, and colorful AI image-generation art previews on the right screen. Stage spotlights, floating musical notes, glowing star particles, confetti sparkles, bokeh dots, and dynamic diagonal lens flares fill the scene. Style & Color: Vibrant anime digital illustration, high contrast, glossy finish, saturated palette of neon pink, radiant gold, deep purple, and electric blue, dramatic concert backlighting.
