cool, cool.... I liked the slow motion affects you did there and how the blood was animated, executed very well! One or two things I would suggest: EASING. It looks like you could use some easing when landing or jumping in mid air, stuff like that. Also, try using double frames in some actions to slow down some movements and to make it look more natural. Good thing you went to animate when boredom struck! Hope I helped (sorry if I didn´t), nice work, and I hope I see more!

liked it. Nuff said.
