Improvements?

I was pretty happy with how this game: Game 5389769 turned out. However, at least two of my moves I think were very unsound and probably total blunders. Was I just lucky here that my opponent blundered back at me?

Quick improvements for White:

25.Qxf6

28.Rxg7 Qe7? 29.Ng6+

Nice game.

Ah yeah, that move 25 was really dumb... Thanks for the help.
