Maya Walk Cycle.

Animating Burt walking wasn't tooo bad but there is something I'd like to adjust given the chance to work on it again.. He has a slight 'limp' in his step. I want to make a smoother walk cycle and also try out different walks, for example a slow, lazy walk.. a feminine walk, one with a little 'hop' in his step and so on. The more I use maya the more interested I get in it and the more I want to learn but I just need to find the right pace for myself and take it at that speed. 

I'd also like to adjust the tips of Burt's toes to give his walk a bit more character.
