Very neat, I like the little touchs such as the detail on the corner bricks and the supports under the wooden ledges.
I personally would have given the texture on the white and grey exterior more depth to achieve a rougher, more medieval look, a wooden texture for the struts would have been good too. Maybe make the windows transparent. It's a pain (or pane. Get it?) but I think the soild light blue windows look can really ruin a 3D model.
A good, clean model. You should be proud of it.
I had actually planned on using hand-painted textures for this model but they just did not look right at all. Hopefully at some point in the near future I will re-do these models with either hand-painted textures or real-world textures.
