Looks fine.
SB calling range could contain 99 but outside of that, which hands are beating us? he could easily do this with weaker hands.

Yeah think you played fine. I would call river as well. Think you can size down the flop a bit, but kinda whatever is fine.

You’ll lose to some 99 or maybe K3s, but that’s like 4 combos. If he has 2 worst flushes you’re good. There’s possibly worst value hands in play, and who knows, maybe an occasional bluff(but very unlikely)
