? This is not good. White now forks two pawns, and Black must move the bishop again to defend them.

White attacks the b- and d-pawns, and forces Black to make the only move he can to protect both.

? Dangerous. While Black is in a bad way, I think he is compelled to deploy the knight to f6. Sooner or later, though, he should take on c4 to give his bishop some play.

Surprise! I save both the bishop and the d-pawn, plus attack the queen, with one move! If Black wants to hold his d-pawn, he should now move the queen back to d8. Instead, he gets unduly aggressive and material begins coming off the board.
6... Qf6h4
Just what does he intend to do with that queen? It can do nothing alone, and is vulnerable to attack by the White forces. First, though, I take the d-pawn.

?? I have no idea why he played this. Obviously he overlooks that he has unguarded g7, and that the c6-bishop is hanging, I now win huge material.

This gives Black an ugly choice: take on c6 (or advance the b-pawn) and lose the rook on h8, or take the bishop and lose the rook on a8 plus letting me get another queen! He chooses to fight on in a hopeless struggle.
8... b6
The lesser of the evils, but now he is down almost the value of a queen, and his pieces have nowhere to go so I am up essentially a whole army!
