The Evolutionary Path We Walk

I made this using charcoal for my drawing class. The topic the professor gave us was: "environment". Let me just say: charcoal is really difficult to use!!! You make one mistake and you can't erase it!! DX Anyways, can anyone help me think of a better title for this?? I thought about it for an hour and came up with nothing. Help a fellow deviant out? Well, I hope you like it!!
