This is the cleaned up rough of my self-portrait avatar. I sketched this digitally. With this character/mascot design workflow, I start with the rough.
The sketch is refined in Photoshop and carried over to Illustrator for "finessing". This is the lineart stage.
Well this pretty much speaks for itself. Coloring is completed in Illustrator.
I still like to experiment with the details of my coloring technique, but I'm getting close to an all-around method that works for me in terms of speed while maintaining quality.
