1. Poly count is a bit high for a tower. But it is acceptable.
2. The rock needs some help. It should be a gray rock. That way it can go with multiple terrains.
1. Well made mesh. A lot of detail.
Overall: 4/5 'Good'
Bob's additional notes:
Skrab, a nice model indeed. But, I suggest you do something about that darned rock. It is very pinkish. And seems to stand out amongst the terrain.
