A draw with a 2020 Rated player in an OTB Tournament

This is my best performance in my 17-odd matches in rated tournaments.  6 of them are against unrated players.  I won three  games on  rated players including a win over  1674 rated opponent (and also have a one walk over win).  Though I will not say this is a very good game, but nonetheless it  gave me confidence that I  can give a fight to  players rated well above me.  

Most part of the game, my opponent had advantage but I feel 40th move changed the game and I could escape with a draw.  

Secondly, every player will have ups and down while playing in OTB tournaments.  So this may be a bad day for my opponent.  

Thanks in advance for suggestions / comments.
