Walk Cycle Version 1

I started the walk cycle and started adding in some of the more of the curves seen in human movement but it doesn't look right. I can't get the rig to really look like he's planting his feet down when he walks and it also looks quite slow. I tried adjusting the timeline but it didn't balance out right so I'm going to create a version 2 and start the walk cycle again, trying to learn from my mistakes.
