방 안의 기타리스트 애니 앨범 커버

Cinematic vertical anime album cover illustration in mostly monochrome pencil-and-ink grayscale with selective color accents. A [slim teenage boy with messy black hair] sits on the edge of a bed, playing a [black electric guitar with white pickguard], wearing a short-sleeved white school shirt, loosened black tie, straight gray trousers, and dark socks, his head tilted down in quiet absorption. The bedroom features delicate manga linework, realistic shadows, and reflective wooden flooring. On the right, a desk holds an office chair and an open laptop displaying audio waveform editing software with the title '[未送信の花]'. On the left stands a bookshelf, and a music keyboard/synthesizer lies diagonally across the floor in the foreground. Centered in the upper background, a tall open window floods the room with bright summer sunlight, revealing the only fully colored scene outside: a vivid blue sky with white clouds and soft sunbeams. A fluffy white hamster sits on the windowsill looking out at the sky. [Yellow flower petals] drift through the open window and scatter across the room. Composition: 2:3 vertical framing with the guitarist in the left third, soft bloom, high-contrast backlighting, graphite texture, no watermarks, no extra text besides the laptop screen.
