$10 NL Hand Reading

I'm not good at it but I would very much like to improve. With this hand I can't remember why I raised pf or wanted to play this hand, but anyway... After the flop I feel BB is most likely on a flush draw because of the check call, but he could have trips and is slowplaying. CO could have a draw, trips or top pair, but top pair top kicker might well re-raise here?
On the turn CO bets when I check which is looking more like top pair to me but could still be trips trying to keep the money flowing in, BB check calls again so looking more like a flush draw. On the river if my read is right BB has me beat, CO probably doesn't depending on kicker, assuming I'm right about him too. So is this any good or hopeless? ;-)

standard, obvious flush

ok so good on the flush, but the other guy is more interesting cos if I manage to put him on top pair but perhaps with a weaker kicker I could push the turn. However if he has 2 pair or better pushing the turn would be uncool... Is it possible to be this precise?

I know it really seems like he has a flush, but with really good pot odds this is probably a call. Streets were played fine.
