Lou Romano (The Incredibles, Powerpuff Girls) recently had his own personal drawing jam where he made dozens of sketches and then painted them digitally. He writes on his blog, “These drawings were done one right after another without any plan in mind. Then they were scanned and painted digitally in the order in which they were drawn. The goal for me was to get ideas out of my head, on to paper and into color as fluidly and as quickly as possible.”
The results are all posted here.
