So uh... I've been using photoshop since like 2002? And I just now thought about using it to replicate real media.
godddd, I'm never going back!
I really like the way you do your hatching when you shade.
you should see the Lakitu I did in the back of my lab notebook! (well I guess you can't unless I scan it...) My notebook is quad-ruled paper, and instead of doing different colors, I did different weights of crosshatching. It's pretty sweet
