Don't just c-bet for the hell of it and definitely don't double-barrell the turn nothing but two overs for the hell of it. Have a reason for it and factor in position, number of opponents, board texture/hand ranges, etc.

What are you doing on the flop in this hand? I don't like your bet sizes at all. You're in a 3-way pot, where someone can have a great second-best hand like 66, TT, KQ, 98, etc. Quit giving the odds to draw and bet. If no one has anything, you're not going to get any calls anyway, so just bet at least 1/2 pot here and same goes for the turn. You have top set and you want to get the money in by the river. Taking those lines is a sure way not to do that, regardless of the outcome of this hand. Just my .02
