Pencil on paper, for a change. I just added a few extra tones in Photoshop with the mouse (sigh), since I have no tablet with me now.
This guy is Ilraavel, a villain of Shores of Haldun (Dragon Coast), a wannabe God who was once an elf but changed into a sort of odd "fishman" after playing too much with evil magic. The actual character in the game doesn't look like a Star Trek character like this one, but I thought he could be rather funny with a look like this, slightly ironic as well.
