Hey, great pictures! I really like the composition on them, especially the second and third ones. My only suggestions is to stretch out the tonal range a little bit. The skin color seems a little flat and gray, even the parts that look like they should be blown out just has a gray cast to it, there's no real highlights that pop out at you. That's just my opinion though!
Like the first two very much, like the third but find the first two unique in composition and in shadows and focus. Cool.
