Layout of a professional VTuber live streaming screen in a horizontal 16:9 composition. Anime-style 3D CG cell-shaded rendering as if rendered in Unreal Engine or Unity. In the center, a 3D avatar character with [brown hair, short twin tails, red eyes, and slightly pointed teeth] sits in a themed gaming chair matching [a room full of donut motifs], facing forward and talking with animated hand gestures. In the foreground, a streaming desk displays a keyboard, mouse, and a mug. The background is a deep, immersive 3D interior filled with themed furniture, wall decorations, and props fitting [a room full of donut motifs]. On the side of the screen, an integrated custom UI chat box frame displays realistic viewer comments in clean digital Japanese font. Along the top, a matching themed stream title bar is displayed. Cohesive, vibrant lighting and unified thematic design across character, furniture, and streaming overlay UI.
