After you placed your queen on near your opponent's king, your opponent moved his king sideways.But I found that he should have attacked your queen with his queen in order to exchange it.Then the game would have been nearly equal.Another option for your opponent would be to move his queen instead of going for the exchange.But still I find black being ok even in that variation.
Where did my opponent go wrong?
I would choose to move the knight to Ng8 or Nh7 on move 14.
These moves protect against a bishop sacrifcise, and make room for the f8 rook, and your darks bishop plus queen to come help defend, on f6 for example.
On move 19, he took on your queen, Qxg6 # mistake, while he should have actually taken on your bishop, gxh6. You'd have checked his king Qh6+, but you'd have ran out of your check after that move, coz Qg6 check is no more possible now bcoz of his queen. So he'd be a piece up for the 2 pawns down. So he could still win the game, as you didn't have any other minor pieces near the king.
Instead of f5 Ng5 would have solved all his problems because he will be able to exchange your Bishop on e3 with Bg5 and thats pleasent for him.

What are you talking about? You can't move black Ng8 b/c the black king is sitting there. Never mind that the knight is on the adjacent square. Are you even looking at the right game??

What the heck are you guys talking about ??
Thers is no possible gxh6 on move 19 !!

Completely correct. Most of his pwans are on dark squares and yours on light squares so the f5 break and exchanging light squared bishops was strategically horrid.
not only exchanging his better bishop but first weakening that diagonal

19...gxh6 20.Qxh6+ kg8 21. Ng6+!

I know, I know, in the end I was a bit inefficient, but where did he go wrong?
Ps. i have analyzed this but not found any mistakes. I guess in the opening he allowed d5, but was that the main mistake?
