Calm Bedroom with Layered Natural Materials

Use the uploaded room photo as the edit target. Produce one photorealistic interior design concept from the exact same camera position, framing and perspective. Preserve the room footprint, ceiling height, structural walls, window and door locations, door swings and visible fixed services. Do not expand the room, invent openings or conceal inconvenient architecture. Infer scale conservatively from the reference; do not invent measurements. Redesign the bedroom as a quiet natural-material retreat. Keep the bed in a position compatible with the photographed doors and windows; use a low upholstered headboard, warm off-white bedding, muted sage accents, compact oak bedside units and linen curtains mounted without blocking window operation. Add a wool-look rug and softly layered bedside lighting. Preserve the existing floor and avoid adding a false architectural recess. Match furniture perspective, contact shadows, reflections and daylight direction to the source. Keep furnishings realistically scaled and routes visibly usable. Remove only loose clutter and replaceable furnishings needed for this scheme. Return a single finished room image with no before-and-after panels, people, labels, captions, logos or watermark.
