I like all of them, especially that one you had trouble loading that doesn't show up in a thumb. The white highlight areas are really solid and carefully constructed.
The legs on your figures look a little long and lanky, but that could just be your model. Still, these are pretty rad, and I'd be proud of them if I were you. I just wish you could post some higher res versions so we could see them better. Then, I could give you more solid feedback.
