gpt-image-2 プロンプト - 夜のバンド練習を描く漫画見開き

A two-page black-and-white manga spread set in a nighttime high school band rehearsal studio, drawn in polished modern shonen/seinen manga style with detailed screentones, dramatic lighting, expressive speed lines, and glossy instrument rendering. The scene shows 4 visible band members in school uniforms: a surprised teenage boy with messy short hair at guitar and vocal mic, a calm beautiful teenage girl with very long flowing light hair playing electric guitar in the foreground, a petite long-haired teenage girl at a keyboard, and a drummer in the back whose face is intentionally obscured by a soft blur. The studio has large windows revealing a city skyline at night, hanging ceiling lights, amps including a visible Marshall stack, a drum kit with a band logo on the bass drum, cables, and a wall sign reading “Beat Box.” Compose it as a printed manga spread with 7 panels total across 2 pages, including gutters, page borders, and page numbers 13 and 14 at the bottom. Left page: 3 panels — top panel with the shocked boy turning toward the girls and a large Japanese speech bubble saying “え!?”; middle panel is a close-up of the long-haired guitarist girl with a calm expression and a Japanese speech bubble saying “……別にいいよ”; bottom panel is a wider full-band rehearsal shot with all 4 members in the studio. Right page: 4 panels — top panel is an explosive performance shot with the boy singing and playing while the long-haired girl plays guitar, with large sound-effect text “ジャッ”; middle panel is a dynamic close-up of the long-haired guitarist playing intensely, with flowing hair, musical note symbols, radiant speed lines, and the keyboard girl visible in the back; bottom panel is a close-up of the boy’s stunned face with soft bokeh and a vertical Japanese speech bubble saying “……あれ”. Emphasize the emotional contrast: awkward surprise turning into admiration as the girl’s guitar performance changes the mood. Use monochrome only, no color, authentic manga lettering, cinematic framing, layered depth, and highly detailed hair and instrument strings.
