Everyone wants mentors these days. I can look over your animations and give advice, but generally it will be the same advice I give in the forums. To be honest, I'm not really good enough to be a full-blown mentor. I wouldn't consider myself higher than med/high beginner. Still, if you want me to I'll do it. Same goes for anyone else.
For that recent animation, you still need to work on the easing. Every movement starts off slow and builds up to full speed. When the guy is flying across he should be losing height as well. I'll post an example in a minute.
