I was recently playing a 5+2 game online and felt like I messed up the endgame. It's upsetting because I just felt so lost and wasn't sure what I should have been looking for. Anyone wanna help?
For reference, here's the game on chess.com:

And here's the pgn:

I (with the computer to support me) think I could have had a small advantage with 18...Bd6, and I regretted not playing that as soon as I played 18...Bf6 instead. He didn't punish correctly, at least. Unless anyone disagrees?
With all that out of the way, here's where I really want to focus from, after 21. Rfe1:
I feel like I, black, should be doing well here. The exposed white king and weak f-pawns look like targets for my queen. With the rooks and queens on board, I didn't think the passed yet isolated d-pawn would make it to promotion. And if all went well, I thought the 2 to 1 pawn advantage on the queenside would be nice for me.
But, I don't know quite how to make the win happen, and as shown in the game I was definitely confused. It's not that I ever expected to lose, but I thought I had a shot at winning.
One more position, after 51. Rh6:
It's a tablebase draw after 51...Rd4 52. Rxb6 as played, but 51...Rd2+ 52. Kf3 Rb2 ? Can I win that?
