I love it! Reminds of the artist drawings they do for the champions in League of Legends.
Anyway, I really like it. I would always mess with the sandbox editors in games like Unreal and the Source editor; people make some crazy ish o.0
The house looks nice in my opinion but then again im no expert. The only thing I can see and critique on, if you don't mind, is that it looks too "blocky". The edges are literaly perfect. I think if you could round them out a little bit, like sort of make it look like the building has been wheathered or been through a couple of years it would look great. Again, just my opinion.
Deffinitely going to be awaiting more like this!
