The photo looks washed out. Higher contrast possibly would help. Also, I have to take your word that it's Bon Jovi. From this composition I'd never know.
It may have been hard to get this close, and this may have been the only opportunity you had to shoot this, but it would have been sooo much better if he had been looking at you.
It's an ok snapshot and a nice keepsake of the concert, but imho as a standalone photo its somewhat lacking, particularly in this challenge. You can barely see the performer's face, and the colors are kind of washed out. You might try cropping out some of the sky above his head, and cropping the shot at the elbow instead of the wrist to eliminate the distracting trees in the background.
