awesome work !. you really know how use the program. I have a question for you, when i saw the destroyed blades, i feel that kind of deformations look a little weird. is not just that they break or bend with the impact?
Made that in Blender? Damn I'm jelous, wish I could make something like this *I don't think your using the internal renderer either, at least thats not what it appears to me anyway given the level of detail*
