Elegant Room Mockup with 16:9 Framed Painting

Create a mockup image of a horizontal 16:9 framed painting hanging on the wall of an elegant room. The room has a cool-toned color palette, using shades of gray, soft blues, and hints of white. The decor is minimalistic and sophisticated, with high-end furnishings such as a sleek sofa, a stylish side table, or a modern floor lamp. The space is brightly lit with clean, natural lighting that creates a fresh, airy atmosphere. Large windows might be present, casting soft daylight that enhances the room's cool tones, adding depth and contrast to the scene. The focus should be on the painting, but the room’s ambiance should be calming and elegant, with subtle shadows and reflections.
