Nothing more you could have done there (except perhaps bet a bit less on the river). That's just bad luck. You had to fold the river.

When there is a QJ on the board as well as two flush cards if you turn a set you have to overbet there. The problem is, at the limits you are playing a fold to a 5 dollar bet on a flush or straight draw could be called. I was just say to bet the flop. You were obviously beaten on the river.
