I agree with Martin. Also a bit more detail to make the room feel busy and less empty. Light switches, wall sockets, a glass of water, a plant, a waste bin, books, etc. It doesn't need to be highly detailed or modeled, it can be low poly, it's just to bring some aliveness to the room.
Ha! Yeah. I made the bed with a bump in it to denote a pillow. I must have plumped it up three times. STILL CAN'T SEE IT XD
Oh well, I'll take it as a good lesson in lighting.
