SU OC: Obsidian (Home World)

And now for another one of my crappy Steven Universe OCs! 
This is obsidian. Obsidian is a type of volcanic glass that has very sharp edges and is often used to make surgical knives because it makes such a clean cut. This is why I chose her weapons to be daggers that can be thrown from a long distance. I made the gem in her left leg to look as though it is stabbing her to represent her skills with these sharp objects.
