Painel de Fundo de Quarto em Mangá Monocromático

Using the reference sketch as a layout guide, create a polished black-and-white manga background panel of a shared bedroom. Maintain the one-point perspective composition: two beds framing the foreground on the left and right, a central floor mat leading back to a recessed doorway, a wall clock and book-filled shelf on the left, an acoustic guitar leaning against the left bed, a bulletin board area on the right wall, and a potted plant with small storage boxes on the right. Replace all rough construction lines and annotations with crisp, professional manga line art, screentone shading, fine crosshatching, and halftone gradient dot patterns. Add believable interior details: rumpled duvet folds, scattered paperback books and papers, pinned memos on the corkboard, a shopping bag on the floor, and wood plank flooring visible at the door. Present the artwork as a single vertical manga panel centered on [pale lavender] comic manuscript paper with faint crop marks and margin guidelines. Crisp monochrome ink aesthetic, with no text or loose red pencil marks.
