Busted Staight draw but worth a river bluff?

[mickb70]

Villian is 30/18/4.5 over 45 hands. I don't think I bluff nearly enough especially on the river and this seems a good spot. Not sure what to make of turn and river bets. Is the 1/4 pot turn bet small enough to almost be a check? Do I pull the trigger here? how much? and why? Could/should I have fired a shot on the turn?
