Been iterating on this guy for awhile now.  Its a zombie for a tower defense game.

I only have one angle, so I still need a walking side animation and a walking away animation.  Any advice on creating a side perspective animation that would work with what I have would be great.

Feedback? I like that he has a little bit of a limp. Im not sure I like the proportions. I'm also not sure if hes too big or not.  And lastly colors, I've tried keeping to a color palette but i might need to reevaluate.  I chose a blue, a brown, and a red.  Then I use two levels of semi-transparent black layers to get the shades.
