His mistake, or my 'strong' game?

So, I played this game online today against a player who will remain unknown. I was just wondering, if it was my "strong" game (Yeah I know, I made mistakes too.) which won me the game, or the bad mistake he made, losing his queen?

I play black.

if you're looking dangerous, always look for the mate.
your opponent blundered yeah, but you took advantage from it.
I think only you can say whether it was your strong game or his blunder.
But I think you did fine
