I like the idea you had with the photo and it is fun and creative. Points for that. I think to pull off the evil aspect, I might expect to see more translucent green or bright red in the eyes. Right now when I see the subject, I think more of "Dirty" do the burning(?--sorry, not up on my post processing skills) effects used. 6.
Funny expression and certainly interesting to look at. This should find it's way into a frame in his room at home. :D As for the merits of the photo in a technical sense the composition works, the exposure and focus are fine. I'm thrown off some by the post-processing. It's very heavy-handed IMO and doesn't seem to fit. JMO of course. Good luck in the challenge.
