You need to work on your bet sizing. Your preflop 3bet was way too small. It should be at least $1 and as much as $1.20. Your flop bet is also too small; Make it at least $1 here and preferably more to build a pot and charge draws (I realize you're not worried about hearts because you have the Ah, but you can get them to call a lot more than $.4 so you should). Your turn bet is also a little too small. Villain's line on the turn is scary, but you could possibly still be ahead and if not are getting a cheap price to draw to your nut flush. I want to say that you should fold the river, but I know that if I'm at the table I make a crying call here (possibly a leak of mine) so whatever.
