On the left: watercolor on moleskine. On the right: digital colors.
The one on the left was done after the one on the right. A lot of people couldn't figure out exactly what was happening when I was working on this, and to be honest, now I can see why. It was intended to be a final rendering for a conceptual illustration class last year; and this scene tried to capture the climax of the story I had come up with at the time.
End result: meh.
I did learn some nifty tricks in the digital version, however.
