You don't have a complete walk cycle for all those directions in the 2nd image, do you? If so, would love to see them.
The animation is great.
southeast walk cycle - the angle of the foot right before planting is rather acute; ought to be more perpendicular with ground, looks painful.
And perhaps just a stylistic choice, but the arms are a little orangutan.
Overall though, very well done. Nice and lively.
Tried a 1px head bob yet?
