I am being broad brushed because I am talking about on average and generalities. Yes, of course there are black players who are very good and white sprinters who are very good, but if the average of a population if considerably lower, the best just will not stack up to the best of the higher average  population.

For instance the link you posted is the first black GM in history. Could be assumed to be one of the very best in history. His rating is 2443 compared Carlsen's 2872. But, this greatest chess player comment is really arbitrary. Of course, not everyone wants to play chess at all, and it is not all about intelligence. I am just a chess fan so I picked it.

What I am implying is there are genetic differences in the once genetically isolated populations which were naturally selected for in very different environments. And the averages of the populations differ.

I feel if something is true it cannot be racist, or if it can the definition of racist must be reconsidered. I do not have these views because I am hateful or racist. I just think this is the way the world is.

Races exist in a way, as in there are groups of people who were genetically isolated for long enough periods of time for the observable differences to arise. And race continues to exist just as in dogs. There is a reason blacks always win the sprints in the olympics. And there has never been a black world chess champion.

Your last edit makes it clear it's a puddle, so you've accomplished that part.

This is just an idea for another direction you could go with it:

I would drop the head turning. In my opinion it ruins otherwise good animations more often than not. It is, of course, also completely unnatural.
Head turning makes me think he is walking alongside a long line of naked women so with each step he furtively glances in that direction and quickly regains focus forward.

Also, you said you forgot about the body bounce.
You should try to not think of it as the body bounce, but rather think of it as absolutely necessary to keep the correct proportions of the legs. When legs bend the absolute height of the head has to decrease or the body would grow longer midstep.

Overall I really dig the style, though.

It is important to reference life when possible, I think. This girl's body moves when she walks. Her body is higher up when her legs are vertical straight under her than when her legs are bent at an angle. A bent leg must give up some ground to a straight leg.

Also, the torso moves when walking. With the current animation, the arm stretches one way from a fixed position and then comes back and stretches the other way. Allow the shoulders to move a pixel or a two with the arms to show slight rotation.
