DeviantART is a vast, thriving online community of artists, writers, and
photographers of all sorts. My own gallery includes a lot of different
stuff. Much of it is artwork from Thunderstruck -- stuff that I
have not put on the main website, but which might be interesting to you
if you're a fan of the comic.
I also have a lot of other art from my many sketchbooks at different
levels of completion -- some very rough, some fully colored and finished.
These include my drawings of dinosaurs, fantasy creatures, and
characters from stories I've written.
A large portion of the gallery is dedicated to drawings from the
"Wakatu" campaign. This is a pen-and-paper role playing game that I
run as GM for my wife and several friends. It's set in an alternate
medieval Japan called Wakatu, with lots of magic and demons, gods
and dinosaurs, and superhuman martial arts. In order to help my
players visualize the world better, I do drawings from the campaign
sessions as often as I can.
In fact, I did a whole comic based on the very first session. That's
"Dragonfly Wind" ... and I'll tell you more about that below.
