I got bored so I colored and edited a manga picture to show what Orochimaru would look like if he took over Sasuke's body. He doesn't look quite so emo. Orochimaru is keeping most of Sasuke's looks so he can trick Konoha and Itachi. Sorry for the low quality of photobucket. Atleast I can show the head pretty clear. Half of the body is cut off. The full picture is here. http://i156.photobucket.com/albums/t13/Malignant_Manor/Orochi-Sasuke1-1.jpg 

See them before my bandwith dies.
