Your flop bet is very weak.

hmm true, i should have bet $2-$3

Raise more preflop;make it like $3 to go.

Bet more on flop;turn I call unless it is a rock or TAP.

Agree with the other posters but I think popping it to 6xbb is tipping your hand preflop, unless you're always raising that much. I'd keep it at 4x (+1 for every limper, yadda yadda yadda). Hit the flop harder, 3/4>pot.
