hello mate, an equally beginning chess player here to give some feedback :) Your opponent made some very basic mistakes, which is bringing his queen out too early and forgetting about it lol :) if he didn't lose his queen he could've caused some more damage. I think 7. h3 is one major mistake you made, you should avoid moving your H and A file pawns unless it's absolutely necessary, it also revealed your king to possible enemy attack. Try to keep your pawn structure solid around your king :)
Good live game

I played one of my best live chess games ever (Don't judge me, I'm only about 800-900)
