I like the flame capture (and that's saying something after having looked at WAY too many "Fire & Ice"'s in the opposites challenge), and there's certainly no confussion over the "bad habit" depicted. If there had been a way to capture a little less of the blues on the right side of the shot, it would have been just that much better in my book, but it's still a solid shot.
The concept's right, but the picture's too small. The background should be all white or very blurry, so that it would help draw the attention to the flame. The lighting on the subject's face by the flame is great! Try to make the picture bigger the next time. Nicely done! [Edited to correct a minor spelling error.]
