Better ending?

Hi, I'm interested in comments please. (This is actually the 2nd attempt at finishing this game, as I totally messed up the original and blundered my queen, and though I did win in the end it took 60 moves...)
So this is replaying against computer from the lost queen position. I'd not seen this opening before, and just tried to use basic principles and I don't think it went badly. By move 24 I'd obviously got an advantage of sorts, and I'm wondering whether there was a better/quicker way to continue. Or any other comments about defending that opening. Thanks for looking.
