Analysis help

I would really appreciate it if someone or several someones would help me analyze my games. Here's one in which I don't think I made any major blunders:

Your first mistake was to move the queen unnecessarily with 6. Qd3. This is a positional error: it lost time and also reduced mobility by blocking the king's bishop from c4 and b5. You may have been concerned that your queen could have been attacked on d4. While this is worth realising, this is not reason enough in itself to move a piece, especially a centralised piece. In this case, the only move that can threaten the queen is c5, which is a move that is bad for black, making the d-pawn backward and not helping the development of pieces.  Hence nothing to fear.

I haven't given any analysis here beyond a move ahead. The reason for that is that before you analyse positions, you should always be thinking of positional factors like these.

While 6. Qd3 is a significant positional error, it is not a losing move. But two or three such moves might lose a game with a strong player, so it matters. To look at it another way, if you gain a few positional advantages of this size, you should have a chance to win a game, so it is not insignificant. 

Good luck!

Yeah, I did get lucky (I do realize that the mate could easily have been prevented by, say, 32 ... Rf6!) but I had been pushing him pretty hard and thought he was getting frustrated. That night I set up a best case scenario with conditional moves. The next morning I found an e-mail that had arrived at 1:40 AM saying that I had won the game (my opponent lives in Ireland). No complaints! And thanks to all those posting!

Lots of blunders in this game.

By way of one example, on move 30. Rg5 wins the queen the next move by force.

It actually just loses the rook for nothing to 30...hxg5.

Oops - d'oh! That'll show me to spin through a game and post an opinion in a few seconds.

Um... neither of his rooks could reach g5 on move 29 or 30. Mine could, but that would have lost the rook to the pawn. I am more than a little confused.

EDIT: Never mind, I understand: Y_Ddraig_Goch said that already. Sorry.
