I think it's probably an actor or maaaybe another kind of famous person. I can't 100% tell if he's in character or not, but I think not, because he's dressed casually and looks like he's just having a good time. He looks amused, and I don't know what the joke is, but he also looks friendly, so that's okay. :D I think you like him. There's an about 50/50 chance he's called Chris (aren't they all?). I think your icon mostly says you like this guy and his sassy eyebrow, which also says you're fannish; and it feels easy-going, like maybe you're not taking everything/yourself too seriously, but any sass is good-natured.
