How's my river play here?

[Crispee]

Foxwoods 10-20. Villian just sat down for 1 round and I can tell he is pretty loose aggressive. But only have a small sample to go on. LAG open for a raise UTG +1. Folded to me I make it 3 to go on the button with 77. He makes it $40 I call. HU to the flop.

Flop: 743 rainbow. He bets, I raise. He makes it $30. I just call.

Turn: 9, He bets I raise, he calls

River: Q, He leads. I raise. He makes it $60.
