First of all I think you should have made it 16$ preflop.
Second, I think your flop bet is very weak. You should have made it 30-36$ instead (Close to or a potbet) Dont forget you are up against TWO opponents!
You dont have a made hand and if they can fold to 30-36$ is wonderful. Your bet just want them to call with a lot of hands that can kill you.
You do hit on turn, bet it! getting raised? Start to calculate the odds!
River: Bet and hope someone pays of with a straight or a lower flush? What else where they callin allway with?
