I don't really understand what the painting is supposed to be. Other than that, this is pretty nice. The only thing I don't like is how the flowers go over the roof.
Yeah, rugs are a pain in the ass. The first rug I drew was an elaborate oriental rug, and it looks okay, but it doesn't go with anything. Honestly, the best rug I've drawn so far is just a solid red with a pretty simple yellow border.
