Yes many styles. The eye was done in a layered way, airbrushed a circle white on the red eye part, then from the layer below i took the original red again to draw lines off the back through white airbrush again. Also i used (hard to see) difficult types of red, which makes it more vivid. For the main picture it is shaded a few times, and then the background is shaded too a few times. Shading and erasing are really powerfull tools to set the mood.

After i saw a gorilaz picture (which i drew before) i thought i shouldnt copy such drawing, but make one of my one, so i imagined how one of them might have looked like before he got famous )

Must have been outlaw type of guy, lot of piercings and sing in clubs who dont see the light, and smell like... bwuaah,,
