At first, I was going to say you played it perfectly.

But Villian raised the flop. He's much more likely to have a T than 33 or 44 (the turn all but ensures he doesn't have 44). Your smooth call of his raise led him to believe you had overcards, so he bet and slowed down on the turn. He woke up on the river to make his lesser two pair, not realizing (or forgetting) that an overpair in your hand beats him.

What the heck ... I say reraise the river.
