This was a second attempt at taking a line drawing of a griffin and coloring it in. This time the entire coloring job is made from an Airbrush tool.
I changed my process a little here in that in order to touch up the painting, I turned off the black lines entirely and kept painting until the griffin popped out from the background without them. I then turned the lines back on, but found I had to change some of the strokes and add some more to account for the new direction the painting under them had went.
Having the white and red lighting reflecting off his feathers was a happy accident, when I drew over him with my brush while it still had sun color on it, said “oh, that’s cool!” and continued to give him highlights everywhere.
