Very nice, did you use stain to get the wood to look like that or did you actually burn it?
A couple of notes on your door:
First, you want to have the door go all the way to the top of the cage. If you don't want a 6ft tall door then keep it like you have it just with the door up to the top and the space that doesn't open at the bottom. Having it the way you have it now will obstruct your view of the cham.
Second, and for future reference (no need to change it now) next time you build a cage the door doesn't have to have those metal braces on the corners. Cutting your door joints at 45 degree angles and screwing them together is plenty strong enough.
