I just switched from brush to line tool (it seems easier to me) and just cant seem to get run animations down. Help?

Main Problem: Going from stationary/idle to running

Well if you want to go from stationary to running first work on easing, After that it is simple , go from a basic idle, to a basic walk and the walk leaning forward to a run :3

Easing Eh? Thanks :D Ill do some practice with it.
