Lately I've been working on some stuff in my sketchbook after a while of neglecting it. Here's some studies I had decided to do to start back into it again. The references for these are various ref pics of boar and javelina skulls I've got laying around in my files.

These managed to come out nice enough that I'm offering it as prints on inprnt.
