Hello McHallow,
Preflop: Way too loose raise with QJs, I'd likely just fold such hands from UTG, you will need a lot of postflop experience to play such hands profitable being mostly OOP.
As played
Flop: Bet near pot, maybe even pot, try to put maximum protection from any kind of higher FD or maybe even against a set which is trying to get his FH.
Turn: Bet/Call is totally fine, since he could still have hands like overpair with FD or even maybe just 3x what was really bad played on flop. Also could have a worse flush, but I wouldn't really get it in here since we only will get Called by a better hand, unless we know the opponent better.
River: Calling is totally fine, we still beat a lot of his betting range here to make the Call profitable in long run.
Best regards.
