NL200 - QQ overpair on flop

[ToFarGone]

One of my big leaks is that i'm playing to nitty. Here's a hand where i'm not sure if my fold was ok or if it would've been better to shove over his raise.

Villain is 34/15/1.28 over 350 hands, flop AF is 2.73. He called fast preflop and I don't think he plays a draw this way.
