/ic/ - Artwork/Critique

I wanna try to get deeper into backgrounds / full pictures.
Aside from an obvious lack of overall details, how are the values?
Looking at it zoomed out (like a thumbnail) I think the light coming from the window creates too much contrast and ends up leading the eye towards it, I wanna make it clear that the room is all dark, so even tho it's nighttime there's more light outside, hence the light on the room comes from the window.
If anyone knows a good reference for this it'll probably help a lot.
