Not sure what villain is calling flop and turn with. Only reason to bet is to try to fold out better hands, and I think you are too strong to turn into a bluff. Villain is likely not folding any better hands to anything other than an overbet, and may call an overbet anyway. Only worse hands that call is 5x or 3x, and not much in range there. Looks fine to me. Maybe you lost some thin value to a hand like A5, but nothing to lose sleep over.
