Overall i like it. Its a clean with realistic feeling.
Below are my suggestion to further to further improve the composition for your consideration:
-Ambient requirement to be produced by one light source seems need to improve, propose to add light sources such as task light and accent light.
-Propose to change the material or design of tv rack it seems like a work station.
-change pillow, use a lighter colored textile
-Pendant seems floating add base plate.
-Depth of wall cladding at the picture frames near the tv seems not enuf.
-Enhance the Ambient occlusion a little bit to emphasize lines.
