Create a sketch-style rendering of a modern and elegant master bedroom. The room should feature a king-sized bed with luxurious, neutral-toned bedding and a tufted headboard. Include two sleek nightstands on either side of the bed, with stylish lamps and decorative accents like a vase or clock. Add a cozy seating area with a small armchair and a reading lamp in one corner. The floor should have a large, plush area rug, and the walls adorned with minimalistic artwork or a textured accent wall. A large window should allow natural light to flood the room, and sheer curtains should drape gracefully. Add a subtle walk-in closet entrance or a door leading to an en-suite bathroom for added luxury.
