I'm trying to find a comment to help you improve but I can't, nor can I substantiate any criticism. I like it. It's so well balanced. You look at him, he beckons you into the photo and insists that your eyes start there, then as you lead away you find the people in the background and wonder why is he alone? And yet he's somehow better off because he's with the viewer.
It's a million possibilites.
Good shot.
I might have been more creative with the title... "I'm not with them!" / "Different Class" / "This seat is taken"
