Certainly this don't look as if u had any devastating advantage in the endgame. Just one pawn ahead and right side pawns more likely to reach promotion than not.
Not bad, but I would' t call it a "perfect game". To me, personally, "perfect game" is when your advantage in the endgame is truly unquestionable or overwhelming. Otherwise it's just a good game. Of course all is judged sheerly from the final result point of view 
.
Surely, no (human) game is perfect.. I nevertheless disagree about your statement on when a game is perfect..
You might create a unquestionable or overwhelming endgame without playing even good, simply because your opponent played worse.. And if both players would play absolutely perfect (say engine VS engine) there probably isn't a decisive endgame position either, while the game can be considered perfect (under bounded rationality)..
What I meant was that if I played 'perfect' in the sence that I did not make any clear mistakes or inaccuraties... And surely, my opponent played very good as well, so I doubt if a devastating endgame was even possible..
Hey,,
This is a game I played recently.. I believe it is one of my best games ever played, mainly because of the lack of mistakes and decent positional play..
