Hello wnbMG,
I'd just comment that everyone is welcome to post.

We are learning from mistakes, ain't we? And from posting hands and evaluating other hands we learn, learn, learn.

So feel free to post if you want to.
Flop: Bet it bigger, why so smallish? You are practically telling him that you have a weak hand.
Turn: Myself I would say also that Bet/Folding the turn is still better. Since there are still couple draws even which may pay. Just going for Check/Fold might be too weak. Plus of course we even have the
Q
which gives us even better equity against any range. Also could bet a bit bigger ~$1,20.
As played
River: Nothing much to say I guess, he may easily even have worse sets, 2pairs. For the given odds I don't think that I'd lay it down.
Best regards.
