I decided to do a few cellshade drawings to see how long they take to get out, mainly for the sake of figuring my pricing when I get around to adding them to my offered commissions. Pestis, my fire-breating, perpetually angry dragon son got the first attempt. I'll be making two more attempts to round out how long it takes to make a cellshaded headshot before I finalize the price.
Time taken: 4 hrs.
