A quick little game

Just finished playing a buddy of mine in the Sicilian. He attempted the Dragon variation, and as I usually do, I played f4 (also I often do f3), and the ending result was quite enjoyable.

I was hoping for some input on the game as well. I know it should be put under Game Analysis section, but I was already almost done commenting the game before I realized I required more input.

I think Qh4+ as well as Nc6 would have been his saving graces.I feel my (white's) play wasn't as sharp as it needed to be, and there were some holes in my attack. Does someone see improvements in my f4 vs dragon, or some improvements black could have made, so I can relay some feedback to him?

Either way, a fun, quick game.
