OK. So, it's nice.
Now some constructive criticism.
Your texture scaling is different on all the walls. In the last pic, the back wall is evidently more detailed than the rest. Also there are bricks on the roof.
The windows look nice, I like them.
The door is very large (there is no lintel), there is nothing to support the roof over it.
Finally, I can't help thinking that it may be a little small.
Anyway. Good wip.
you should enter it in the comp, who cares if you don't think it's good enough, if no-one else enters you'll still win!
