This is very good, the music and animation.
Just some ideas: You could work with facial expression and movements.
The guy in the window for example, it might look better if he turned around waving his hands or something :3
When they jumped down in the sewers and entered the pizza place happened very fast, like if something was missing between those places... And what kinda kitchen got handgrenades xD
Anyway, well done! Looked like you put a lot of work into this!
