Good job on the lighting.
The walls and ceiling look like they were cut from a ridiculously huge tree. You should either make the wood panels thinner, or make them something other than wood. Having the wood cvering everything is making the room feel very cramped and closed in.
Those pillows seem to be balancing on one little corner. It looks a little funny.
The light coming in from the windows is too blown out. Its not direct light, so it wouldn’t be so harsh.
You shouldn’t be able to see the lightbulb so clearly through that lamp shade. It looks like there’s no light coming from that lamp, yet that bulb is a bright white.
I like the shape of those little stools!
Great job texturing each book as something different, thats a nice touch.
