I feel like everyone at that ISC meeting had to try this out…but we had a recently graduated illustrator, Matt Houston visit and show us his work as well as an awesome and quick photoshop technique (some of his awesome examples: http://brightsplashes.tumblr.com/)
Had to add a little extra texture to mine, because it was more of a finished drawing than a sketch, but that’s because it’s also my entry for the Time Warp 2014 Fan Art Polooza for the webcomic The Dreamer.
The lovely (and historical!) character of Nathan Hale in modern attire. I think those tattoos would actually be pretty sweet.
