Agree with everything that has been said.
And while I really love the look of it the textures and atmosphere is spot on
I tried to do a paintover of things I personally like, more pronounced shadows and highlights, brighter outside(windows) a bit more color, try and get some objects in that break the brown/golden look.
I also think it looks to empty, I know it's a wine cellar so there will be mostly... Wine but still in a few shots it's so open, that maybe even some foreground objects could help a ton.
Edit: Damn, should have used the latest images xD
