this is quite a good movie. however there are some points i would like to make, ontop of some other reviews.
1) blood and stuff i thought usually divides slightly as it goes through the air, even in slomo. instead of just making it move in a direction, try altering the shape slightly too.
2)the "speaking": could do some work on lip syncing and find a speech generator somewhere, unless your intention was to leave it out. in this case, just improve the mouths.(or mouves? lol.).
