The individual pieces are nicely done, but the perspective is so bizarre I'm having a hard time even looking at it. I'd suggest working from some reference photos if you want to do a perspective piece, and taking some time to learn how perspective works. This should allow you to plan out your piece a litle bit better so that all the pieces work together.

I agree, you need some serious help with perspective.

 I think this, as well as your kitchen piece, suffers from a lack of understanding or use in perspective theory. Although creative and well rendered with a nice colour scheme and brilliant layout, without an understanding of perspective/depth it will never look "right" even if you're the most skilled person in the world.

If you want I can redline this to show you where you've gone astray. There are a few serious infractions made (ie the doorway on the right is angled opposite to how it should be at the top, the floor on the lefthand side is off in angle by quite a bit, and the floorboards don't relate to the rest of the angles at all) and a few less minor ones (a lot of the smaller pieces aren't angled right, but are close) and some funny ones (a lot of the pieces against the wall go INTO the wall! oi??)
