Reminds me of a film I saw on the DAVE school website a few years ago but they had stuff being hit and then blowing up (yeah, I know much harder to do) but it looks like the clips are just stuck together. The render looks good and must have taken ages, I tried 3D Studio Max a few years ago but it just wrecked my head. The video needs more structure with possibly an outcome or a pay off at the end.

Looks good!
