"Give up Smoking"

Nice lighting of the subject. Only suggestion is that if the background would add to the image, then increase the lighting there to show more of it. Otherwise, let it go black if there's no point in seeing it. The almost-black texture there makes you wonder if you should be seeing something there, which detracts from looking at the man.

The shapes in the background maybe is just smoke, or am I wrong?

It's not smoke. Just calibrate your monitor and you see the wall)

I agree with stephen. My eyes really ran away from the subject, they wanted to 'see' what's with the wall. It was just "a wall" as you said, but it would've been better if it was either more visible, either black. I like your photo, still the guy's face seems a bit theatral (pathetic) - but don't get me wrong. Its just not realistic ! Next time, I'm sure you'll do it better.
