I love the way the fire reflects in his eyes. You did a great job with editing the fire into the shot and it looks natural.
While I like the pattern in the background, I don't like the faint traces of it on his hand. There is just enough of it there to make me curious and I spend time staring at his hand trying to figure things out instead of looking at the rest of the image. I think that's mostly a 'me' thing and not something wrong overall though.
His expression is wonderful as well. It comes across as slightly playful, completely confident and slightly smug (it's the curl of the lip). Well done and good timing.
