Terrorist babies are no joke.
I enjoyed the Baby Sitter animation. You've got a good sense of humor. Your animations are indeed entertaining to watch, but you have to, have to, have to, have to work on your movements. I can't pinpoint the problem with what you are doing, but I can say that it looks sloppy. Be patient, young Skywal-- I mean, Pyro. Take the time to move each joint just a little bit in each frame. Trust me, the smallest details can mean a world of difference. And you would do well to remember that each motion has momentum. Ease everything.
I will say this much in your favor: You have some magical camera movements. Use that to your advantage.
Keep at it!
