Your advantage was slowly vanishing in this game.
For your future games, remember that with only pawns on one wing, and none in the center and the other wing can already increase drawing chances a lot, even when e.g. a piece up.
When going for an ending where you want to win, keep in mind that you usually don't want to end up with pawns on just one wing, unless for the exception that the ending is easily won nevertheless.
So, for example if you can choose for a passed pawn on the queenside, or for a pawn up on the kingside, including a doubled pawn (but with pawns only on the kingside), then you might want to evaluate the winning chances with the passed pawn first.
