5NL >>> Bad bluff???

[Larude]

I recently started playing on Poker Stars, because at my previous online pokerrooms there weren't so many tables at the stakes I eventually want to play (I played 10NL and some 20NL, but at 20NL there aren't many games and higher even worse). I deposit a small amount so I started off with 5NL to built it gradually. Now is this a bad bluff because it is not convincing or is it a bad bluff because I first should know my opponent better before considering it (e.g. is he weak tight enough). Villain was pretty loose preflop, but I haven't tagged as a callingstation.

Hero calls because he has two overcards and wants to bluff if a scare cards comes off. If the action comes to bold hero will fold.

Turn: 3[img]/images/graemlins/spade.gif[/img] ($0.47, 2 players)
<font color="#cc0000">BB bets $0.1</font>, Hero calls.

Hero thinks his opponent has a nine almost for sure with a weak kicker, he is getting odds for a flush or straightdraw bluff + any Q or J is very probably good.

River: 6[img]/images/graemlins/club.gif[/img] ($0.67, 2 players)
<font color="#cc0000">BB bets $0.15</font>, <font color="#cc0000">Hero raises to $0.7</font>, BB calls.

Hero thinks a valuelookalike bet of 0,55 will do the job, but it doesn't....

Final pot: $2.07
