My first published comic series was Nature of the Beast. I ended up having a falling out with the writer while drawing the third issue and never completed it. But had we this was to be the cover art for it.
It’s the young surviving mage from the story, Vex. Repeating a theme started with the cover of vol 2. I seem to recall using a photo of Greg Louganis as reference for both.
The art is done in pen and ink, markers and paint. Paper looks like a heavy Mayfair stock I used to buy in loose large sheets and get cut down to custom specs. 15.25×10″ here.
