The animation is decent but needs a bit more work, and try to not end the clips exactly at the last frame/after the last frame of any object moving, it will look weird that a moving object stops all of sudden.
Ah well, leaving that aside I like the whole story line and the look of the scenes, as well as the dynamics, and I really like the fact that you've placed the fracture color after the car hitting you, that gives the impression that the car hit you hard. And for some reason the children creep me out.
Also nice Easter egg, won't say it just to not spoil what is it and when is it.
AND HANDS AGAIN!!!
