A detail of my Tinkerbell sketch, [link]
colorized in about 15 minutes while eating lunch. Photoshop is the best.
Because some people are misunderstanding what this is:
I did a convention sketch of Tinkerbell, using grayscale COPIC markers. One day, while having lunch, I qucily colorized it. It's not some boast about my PS skills; I was just making a point about how easy it is to colorize a piece when all the hard work has been down in the grayscale stage.
