You realize you're all editing the edit...?
Editation is the first step to perfection. Though the place may be wrong to do so, there is a still a beneficiary purpose that comes out of it.
Fizz, anyway in regards to your example, it's much better now in terms of stance, and even color.
Also upon looking at the animation again there is an issue on the side view on the right foot, (second from front), you shed no real movement into it, what happens is that you have a static chain of pixels for that leg, and then it seems that you create a 3rd leg to substitute stepping while at the same time you retain the original right leg. This would partically be the issue with the movement along with the motion effort put into the model to make it walk. Lastly you might want to even out the sizes because as you see the front view is larger than the side view by at least 2-4 pixels which may cause some issues down the line of production.
