It's a very goos idea but maybe you should accentuate the bad and the good side a little bit. Good luck author

the good side kinda looks like the singer from My Chemical Romance. good work

Too dark, no background. It just looks like 3/4 of only a face, with no real jaw to speak of. Also, it visually reads as "evil vs. good," since the "evil" side is on the left; should be flipped. That's why twins always pose to match the way their names are presented (e.g. "Jedward," "Mary Kate and Ashley," et al.).

Thanks for the comments. Image updated.

This is one good idea.

Another elegantly realize interpretation of the theme. I am very impressed with the way you have presented your idea. A powerful yet subtle image. Bravo! Definite fav!

Nice work....
