I generally like everything about this, but the follow-through bouncing on some parts isn't as proper as it should be and it just nips at me. Most things move like two or three pixels, but it looks like the knees move one or two, and the legs don't move as much as they should when someone moves down a bit. The hair is flowing to the wind, but not following through with the bounce besides maybe being positioned down a pixel. For the antenna, having at least one more pixel of it move would look more natural (even though you can argue that it's top heavy). I understand have the tits bouncing one at a time at an angle but... more of the body needs to actually move like that in order to make them do that kind of motion.
Basically, she's too stiff for what you're trying to do. These all come off like nitpicks, I know, but they're the little things that build up an awesome piece, and this has the potential.
