It looks nice, but the colours don't seem right - it looks like it's been painted. The walls should look wooden and the roofs should look thatched. I think also there are too many straight lines - it should all look a bit rougher. It might help if some of the buildings were rotated around a bit, so that they're not all aligned in the same direction.
Does the building in the southern corner have pillars around it? Do you have a source for that? It seems a bit out of place to me.
