many inaccuracies imo but its expected at this rating. The main thing i saw from you was that you should have taken his queen QxQh3 on move 29, would have saved you some time....
and there is no reason not to play QxQ and win the queen becuase i dont think you have an outright forced mate anytime soon so its best to just take the material and then force the win from there.
My opponent made a huge mistake here, you'll surely spot it.
I would also need as a beginner some information what could i improve on this game.
