Interior mockup background for wallpaper/photomural e-commerce, vertical 4:5 composition, CLASS C (simple, stable, clean). A bedroom with a large clean EMPTY accent wall — absolutely no paintings, no shelves, no TV, no decor, no picture frames, no power outlets, nothing mounted on the wall. The empty wall is painted in a warm light neutral tone (soft warm off-white / gentle cream) and occupies about 55% of the frame area, clearly framed by a visible ceiling line at the top, a wooden floor and a subtle skirting board at the bottom, so the wall boundaries read clearly. Standard straight frontal camera angle facing the wall, perfectly straight vertical lines, natural interior perspective, NOT wide angle. Furniture sits only in the lower 35–45% of the frame and does NOT cover the wall: a low bed with simple linen bedding in muted oatmeal tones, one wooden nightstand, minimal decor. Everything centered with generous margin on all sides; furniture does not fall off the edges. Simple soft natural daytime light, gentle soft shadows only, no harsh highlights, no strong contrast. Photorealistic, high resolution, no artifacts, no AI defects, clean and crisp. Style: soft minimal, scandinavian.
