effort: 1.75/2 - I agree here. Some stock work would really add to this, and because it's lacking, it almost feels incomplete. I get sometimes simplistic is nice, but this is just too simple. You've got stock work skills, use 'em Cowboy!
look: 2.5/3 - Again I agree with the above comment. I think stock work really hurt this, or lack of stock work rather. Had there been some effects, better blending, etc I think this would be a totally different sig. Keep working on it, I know you can do it.
creativity: 1/1 - yes
total: 5.25/6
final: 5.
