I would raise much more on the flop and bet more on the turn. With a flop and turn like that there is no reason for CO to have any chips left on the river IMO. As you played it, I fold the river.

flop: agreed. which bet size do you think is correct? raise to 10$ for an about pot sized raise?
turn: i didn't feel good about my flush. i was just cutting down the odds for high spades.
river: yes, i think my call was bad. but while playing i thought "hey, 4:1 odds, maybe he has a set, two pair or funny things".

*edit* what's the hand range you put villain on before and after the c/r on the turn?
