Walk to Stop Second Pass Polish

This walk is due tomorrow - I feel like I am mostly there. I want to sleep on it and have fresh eyes in the morning to make any final tweaks. All in all, I know its not perfect, but I need feedback to figure out exactly what is wrong. For me, subtle and highly mechanical animations are the most difficult for me, hence my struggle with this shot. Almost want to start from scratch again now that my method is more solid. 

Cycles are so different from performance pieces, because you are working on everything at once. I think I am pretty happy with it and I am excited to hear what people think of it!
