Fire-breathing monster in the hands of an amateur

Hey folks,

I just played a game on live chess, using the Sicilian Dragon.  I don't use the Dragon very often, as I prefer openings like the Berlin Defense or the Traxler Counterattack, or even the Latvian Gambit.  But I used it in this game, because I am trying to learn it.  I won the game, although in a rather sloppy fashion.  I would like to know what you think of it.

I believe I messed up my attack a few times.  For example, I had opportunities to win the material back and I didn't.  I am not the best person to be asking about this though, because I only have a 771 USCF rating.  Any analysis you folks can give me would be greatly appreciated.  Thanks!
