Endgame with Knight/Queen sac

Interesting. I have to agree with Gabriel_dCF, white captured your queen out of a very strong combination, while you got his queen on a blunder early in the game. White had weak opening and middle game, but he gave you a run for your money on the end game.
I think at the point of the game 32.Kf2 , you would have been better off avoiding trading down. You have doulbe his pawn number, you have two pawns supporting each other on BOTH sides of the board, and his only two pawns are on one side, both isolated.

This is my best endgame ever! It includes a knight and a queen sacrififce.
