Photoshop CS3. It was easy. Basic shapes, a little coloring, and dodge tool to lighten some areas. I tried to do a tutorial vid, but it was too big. I have no idea how people do them and then get it to go on YouTube. It usually says all my files are too big. If you know something I don't lemme know (other than shorten the vid.)
Fantastic use of color, and I'm not much of a fan of the gradient LCARS colors. I take it you're going with the Nemesis LCARS scheme?
Keep at it!
