Very good. over-aggression with flush draw have been one of my leaks for a long time.
For short, on the flop, if you face a raise or a large bet showing strength of Overpair+, it is ususally wrong to push back with bare flush draw due to the lack of Fold Equlity.
At least is high swing style to play.
Of course, if you have a good pair or gunshot with your flush draw, it maybe not bad to be aggressive, to balance.
