I would advise avoiding it, since by placing yourself in the story you run the risk of stealing the show or focusing on yourself. A big ego can derail a story or make a character come off as a douche, and, no offense, but based on your model-esque picture my guess is you have a big ego.
I always stick to using facets of personalities rather than inserting the whole person into the game to avoid that problem, since cognitive dissonance can be a bitch (I have a huge ego). This way I run less a risk of minimizing or glossing over the character's flaws.
Just a thought.
I don't think he has a big ego because of his picture. It's more professional than most pictures on this website.
