horrible, just horrible.
go to beginner thread.
Copy paste time.
In all reality, the beginner's section is where nubs comment on other nubs animation, with a few people who are actually somewhat good at animating commenting. Seriously, I really don't like how everyone is saying "go to the beginner's section until you're good enough", and not giving any crit to there animation. It's as if they're pushing them in there. And I also remember some of the better animators leaving because of the amount of beginners posting their animaitons in a thread. Nubs are always going to exist, and as long as you don't help them, they will always be that way, so deal with it. And remember, you were once a shitty animator, and I'm pretty sure you pissed off many a good animators with your bad spelling and constant asking of ranks.
The animation lacks pretty much every basic I can think of, which includes movement stiffness, choppyness, physics, etc. Try doing some motion tests and try to recreate movements from a video or something that has running, or walking, or jumping. The point of trying to make is to not make animations like what you posted until you somewhat perfect those basics. Then, wrap it together, and make an animation. Hope this helped.
