No, I'm not that good. I explain this on my topic in my signature: I create a character in Skyrim (on PC), then use console commands to have the posture and angle I want, then I take a screenshot. After that, I just put a paper on my screen and I trace. For the rest (colors, textures), I use Gimp. Everything with a pen and a mouse^^A very nice picture. What was the technique? Graphics tablet?
I can make photomontage before the pen when I need elements I can't have in the game (the naked feet posture here for example), but I "fit" all while drawing.
