It's Shikamaru Nara, and as you all se my art is based on wallpaper's!XD Just that you know!;P
This is how I do it (my drawin'g then.XD). I look at a wallpaper once, then take it away. Then when I'm done I take it up and look at it, and if it's not how I wanted it I do the same thing again (with all my drawing's) LOL!XD
