I think that hat rack is just a bit too small - don't people usually reach up to put their hats on those things ? And I think I've only ever seen them made out of wood for some reason ! :)
Also, if I may, I think your shadows are really very black and could do with being a little less dense, and the floor seems a little evenly lit compared to the rest of it, or perhaps it's just a little too bright ? Lastly, whilst I appreciate that the richer people are the less taste they tend to have when home decorating, are you sure you want the red of that carpet next to that orange on the floor ? ;)
