I think it looks great~ It makes me feel like I'm... sitting at home, relaxing. Though, I must say, charcoal drawings have always made feel a little dread, so I kinda feel that something awful is about to ensue... but don't worry: it's just a personal thing, and it has nothing to do with the quality of the artwork itself.

I like how to you managed to portray the fur on the dog: it looks good :3 As in, it looks close to actual fur, at least in my eyes~
I've been looking at the piece for a while, and I'm already seeing things that aren't there, haha.
