QJs - Too fishy, too aggressive and too passive?

[Wired Jokers]

I don't know why, but I need a checkup.

Just sat down, so no reads other than it seems that most players are pretty loose, and will easily cold call raises, as seen in this hand. I thought the pre-flop call was close, but OK, since I reasonably thought others would come along.

Flop: too aggressive w/the three-bet? Do I want to keep people in here, due to my top pair, decent kicker and flush draw? I'm thinking my line is correct here, since the pot is big

River: need work on my river game. Does anyone raise here? Am I that big of a wuss?
