I look at him and just see "your" Snape (isn't that funny?) I never really thought that I had a style of my own until recently. I post Severitis artwork under a different name and somebody who views that regularly pinged me offline and said, "Hey, isn't that Snarry Games "Dream Wizard" yours? I recognize your style."
(I thought, "I have a style?" Never occurred to me).
Playing with your characters is so much fun, because you take the hard part out of it for me. I AGONIZE over my drawings and am never quite totally satisfied in the end. It's the coloring part that gives me total bliss. With you having designed the characters already, I don't have to fret over that part. It's pretty easy to recreate them. And I can color away!
(I was that anal child that cherished my box of 120 Crayola crayons and had all the different colors organzied by hues.)
