Seems fine to me, I don't think we gain much by going smaller or bigger on the river and two mid high cards that aren't hearts work fine as a bluff.

Already on the turn we can play variete of strategys - overbet(QQ-AA as prime), normal bets and possible (not entirely sure) small bets (77-99 region, some Jx)

I think on the river you can simplify to 1 size here, because 3x have better interaction with his range so QQ - AJ(KJ maybe) can still vbet 2/3 and we dont need to go polar with valubetting only Tx. But if arent able to valubet KJ/AJ for example, going overbet would make sense.

I like the combo unblocking spades and hearts, problem here is the runout. On this double paired board, you are not folding any pair beside 22s and get looked up by 44s+ and Ahigh. .
