Windmill turret 3D

Here is a windmill that I have done for a class.
The class before this one, we made automatic turrets, but I wasn't satisfied with mine, so I put a turret in the windmill as a revenge.
Hope you found it funny :)

Actually, I don't know if I can post things that I have done in class because technically it belongs on my school. Anyway, in worst case i'll just delete.
