Hank McCoy college student WIP

It's been a while since I created a new Hank McCoy drawing, so I decided to start on one yesterday. Intended to be a slightly older Hank from his college days. I need to add his glasses in but always get really nervous when I have to draw over the top of a face. So I thought it would be best to scan the image in and get a record of it sans glasses, just in case I screw it up.
