$4/180 AQ on the button overly aggressive?

[94ssimpala]

Sorry if the hand isn't the most exciting, I'm a tournament novice and know I need a lot of help. I just second guess how I play hands and figured I better start posting, not just reading. I just moved to this table 3 hands prior so I do not have any reads. I sometimes think my bets are too large and that I get overly aggressive, but I know I don't want to bet too small. Thanks for any input its greatly appreciated.

The result wasn't good, but that doesn't matter to me as long as I played my hand correct. Thanks again.
