Now, this probably isn't my place to bring up a critique like this, but this is what I noticed when I saw that bottom pic.
Besides the fact the I'm not sure if legs are able to make a slight curve upwards (it could just be a rubber-hose thing or how the perspective is as far as I know), the curve where the boot starts from the leg looks a little broken to me. It's most noticeable to me with her right leg (or the leg on the left).
Then again, it could be broken like that because that's where her knee's supposed to be. Of course, if that's the case, then I think it could be a little higher and the bend looks a bit more natural.
