You should create a new image online when you post updates. When you overwrite the original, one of two things happen: either I get served a cached version of the original image, so I can't see your progress, or the original post is updated with the latest version. So, er, I can't see your progress.
That aside, I really like this. The pose is dynamic, the outlines are crisp. Huge improvement IMO.
Maybe a touch more facial definition would be nice. There might be a couple of places where a shadow could go. I'm nitpicking.
