I have been studying scientific illustration with Michael Cooley this past year to fill in some of the gaps I have in my formal illustration training. Below are a few of my pieces!
The sphere -- my first attempt at "true to life" shading with graphite. It's a little rough in places, but it's a start!
Styrofoam head -- I think this piece is creepy. It is a drawing of a styrofoam head, so the eyes have no irises and the anatomy is not exactly perfect. I think it looks like an alien!!
