First of all, I don't really like your flop / turn bets. I prefer pot or very close to it on the flop and pretty close to pot on the turn. In this case I would have bet $4.50 on the flop, making the pot $13.75 (before rake) on the turn, and then $12ish on the turn. As played, I bet at least $10 on the turn, 2/3 pot doesn't really cut when an ace, a J, a 9, a T and any spade are scare cards.

As played, check-fold is a REALLY weak line on the river against a LAG with an overpair that's very often good despite the flush coming in. I like either a bet-fold (bet $15ish, maybe a little more), or, probably better against a LAG, a check-call.
