multistreet bluffing too risky in this spot?

villain is 13.4/8.2/4 over 180 hands. I really put him on AQ, midpairs and flush draw , so i ran this outrageous bluffing against this guy.
In your opinion, is this too risky or standard? what did you put him on in this spot?

fd didn't get there

Actually, this guy thought a while before folding on the river. Honestly, i was a little bit nervous at the time. FD probably not his holding.

He's too nitty for me to want to bluff this guy very often.

c/c c/c says draw to me tho, maybe AcTc.

I like it, and I think you MUST follow up on river once you fired the second barrel. He's not gonna play a set KQ JT passive again on turn much.

What I'm unsure about is firing again on turn. If he raises then we're not getting odds since he's weak so rarely. A king is usually a good second barreling card, but not as much here. It could hit him enough to continue on with made stuff like KQ QJ. If, however, we know to fire a third barrel when called and that he's calling instead of raising enough then it may be best.

I find multibarrel bluffing vs bad nits/tight stations quite hard to figure. If he was good then he would have either folded or craid flop or donked turn. Since he didn't then we now have to understand how stationy of a nit he is, and that can be tough.
