Portrait of a Pig... (Serial Killer)

[Batteram]

I started this concept last night and got around finishing it today. Here's the link: http://bendavisart.xnapster.com/custom.html

Now as you can see there are two pics. The first one is the serial killer with ordinary light shining on him and in the second, I added a creepy purple glow over his body. He is meant to be in a SNM bar or something, so I thought the purple light would look cool over him because it also blends in with the background and gives the the second pic more atmosphere than the first. However, I am still undecided as to whether I should just leave the purple light or keep it there. I reckon the purple light adds to the whole creepiness of the pic but I am still undecided.
Any opinions on this matter would be nice because I hate it when I can't decide on things like this! ;)

freakily cool- anyway the second one sorta takes away from the original's coloring work but definately makes him look more menacing, as if he's watching you from the shadows. Unless a median between the two is possible, i would choose the second.
