Some sculpture ideas

I'm just a few weeks away from starting up a new sculpture class, and I have been working through some ideas of new figures I want to create. I really like the spherical figures that I've been creating, and I don't think I'm done with them yet. However, I do feel like there is an opportunity for me to create some more angular companions.

The sphere is good, but I think I'm getting a little bit tired with the way that I've constructed the limbs. I want to go more abstract and really make these feel much more alien.
