Half of the animation (just with keyframes an rough)

Full cycle with added ,,jumpy-niss''

Any comments for improvement? Second time doing a run animation and my brain hurts...didt look much up and maybe f**ked up somewhere (like the leg bends a little to much backwards)
First animation was a character that was 3x8 pixels so this is my first ,,serious'' try for a game that is in the works...
