Very nice, clean and crisp! And the little mouse hole is a nice touch. Personally, I would have made the foot of the bathroom sink and toilet a bit more round, like the feet of the table and bed, to emphasize the top view. And I'm having a bit of trouble understanding the shape of the showerhead, since we don't actually see the bit where the vertical pipe connects at the bottom. Minor details though 
Hehe, great! Sadly I'm not having too much luck with the exterior tiles. But then again, I just started.
