Fantastic as always!
Since they're so good, my only negative is the posing in #2. A slight turn towards the camera would bring her rea leg into view or slightly away would make it disapear. Also her front leg seems "squished" in this position. Maybe, you could have placed a small stone or rock under her left hand would have lifted her whole position up slightly, losing the "squished" feeling of the front leg, and you would also have her left hand in view.
I don't want to nitpick, but your very good and I think the small things are what your looking to improve.
I could also be very wrong.
Great set. Keep posting.
