Bad-good animation?

So, I’ve just started animating, I’m awful, but I noticed something.

Bad animations, work.

My first attempt was a human character, that was terrible, sloppy, jumpy movement made it stink of newbie.

Then, my second attempt, a demon/zombie character, also terrible, but here, that sloppy, jumpy movement seemed to make it more disturbing.

I’d like to hear your thoughts on this…

How did you manage to create the “sloppy jumpy” movement? Try to make a smooth one and take a note on that technique.

some of the most grotesque zombie movement ever accomplished in blender happened when some one made an error while importing a bvh file
