A VTuber stream background, in a pastel anime style. A cozy lilac bedroom has a fluffy bed with bunny and moon plushies, fairy lights around a window showing a starry city night, and a small lamp on the right, while the left half stays a plain soft wall where your model can stand.

Create a finished 16:9 VTuber stream background, 1824 × 1024 px. Show a softly lit pastel anime bedroom at night, framed as a real, usable room rather than a character illustration. Keep the central-left 45% of the image calm and low-detail as a clear space for a VTuber model: smooth pale lavender wall, subtle soft shading, no furniture, plushies, lights, bright highlights, or patterns in this zone. Place a large window on the right with a deep indigo night sky and small crisp stars beyond the glass. Add delicate warm fairy lights tracing the window frame and upper-right wall, with restrained amber glow and no bright hotspots. Arrange a few rounded pastel plushies and a neatly folded blanket on a low bed along the bottom-right edge, outside the model’s clear area. Add only a small bedside table and one dim lamp near the far-right edge. Use powder blue, lavender, blush pink, cream, and muted indigo; clean anime background illustration, soft cel shading, fine controlled linework, gentle ambient occlusion, even low-contrast light, lightly textured fabrics, quiet depth. Balance detail at the outer edges and preserve broad negative space for streaming overlays. No people, no text, no logos, no UI, no watermark.
