Charcoal Skull Drawing

I LOVE this design (I know you can see other stuff in the background, but I was having the hardest time focusing in properly, especially since I had to try and hang over the drawing to get a head-on picture...)

This was an up-close drawing of a cow skull, if I'm not mistaken... I loved drawing it because I thought it looked more like a cave than an eye socket from the angle I chose

This is from art class last year- drawn around February, maybe (and one of only two assignments I enjoyed)
