Am I an inveterate LAG? (3/6 NL)

[Superfluous Man]

Haven't been at the table very long. Read on the guy is that he plays pretty standardly, maybe a bit looser than most people you'll find at a full ring table (that's currently playing shorthanded). My image is loose, with a propensity to raise the flop, but not extraordinarily so.

Yeah, I know the preflop raise is very loose, but sometimes I like to throw in that kind of stuff, especially when it's not a full table. Please, be merciless in critiquing this hand, especially the flop play and the turn jam. Please tell me what a donk I am. I can certainly explain my warped thinking after a few replies.

There's no converter for FTP, so this will be done poorly, by hand...

EDIT: I am mainly a tournament player, and I would make this play really, really often in a tournament. I'm trying to use my tournament winnings to learn NL cash games (haven't donked off too much of my bankroll yet). Something tells me that in a cash game, where people can just reload, this play isn't nearly as profitable (if it's profitable at all, at any time). But then again, I also have found that people have a propensity to fold without a big hand here at FTP's cash games.
