This illustration just looks weird to me. The way the the black of his hair recedes to the side and reveals his skin makes him look like he's got an awkward comb over... Also, I'm tired of anti-smoking propaganda. I mean everyone on Earth knows the dangers of smoking by now, so, let's all move on to something else.
I don't know what to vote- I love the look of the image, but it's too preachy for me. It looks like you can make some pretty nice stuff, though, so you should definitely keep submitting ideas. Ahhh I'll give it a five.
