I agree with gster123.
The piece looks more like a Lego castle set. I like it.
The model is ok except for those sharp corners mentioned earlier. The texture work is a bit too monotonous. Try adding some moss on the bottom and vary it on both sides of the castle. You can also change the tone of some bricks on either side to show some weathering and discoloration as well.
Bump maps will also help by adding more depth.
That should add a bit of visual variety.

*Some flags might be a nice addition.
