Help with analyzing a win

I just had a very interesting game in a tournament I played in. The game, with comments are included here too. I'd like your help to analyze the game as I am very new to chess and could easily just bask in the glory of a victory ;)

No but seriously, please point out any flaws in my reasoning, give me black attacking lines that would have lead to my demise, and feel free to include diagrams as that makes it much easier for me (I'm not that  comfortable with algebraic notation yet, it still takes me some time to visualize the board, so diagram really helps). If you would have had another way of playing it out as white, I'd much appreciate to hear it.

After 9.d5?!  if he played Na5, you would have to move your bishop to either d3 or e2 squares. You generally want to avoid trading off a bishop for a knight at this stage as the position is open.

 Your sacrifice is in fact a blunder. 14. Ng5?? gives away the knight for no compensation. You should have a look at your pieces. Unless there is an immediate danger if he takes your piece you should avoid sacrificing and build the pressure slowly. Patience is required in these positions.

Say he took the Knight, You take with your bishop and he castles.  He has an open f-file and is winning comfortably. His 14th move is hence, a mistake

Your fifteenth move is excellent. Your knight is in a solid position,supported by your pawn and your opponent will have great difficulty removing it. 16... h5 is wrong as it weakens his position even more. 18. Qxf6 was the correct move . You should not worry too much about your d5 pawn when you can end the game soon.

Thanks a lot!

I agree. In the line you give to your 14th move he could play 15... o-o. I cant see any real threats after that.

 Even if he played 15....h6. 16. Qh5+ he could probably just play 16.... Kf8 followed by moves like Qe8.

Hey I took a look at the game and was wondering too what rank he was at? But anyways an interesting attack (should have been your 6th move since the doubling pawns was already "forced") that I have discovered on undeveloped knights is to go ahead and take the knight with your bishop so the opponent is forced to recapture with the rook, this prevents the opponent from casteling on that side and makes the game a little more awkward sometimes for him. Now the doubled pawns are not so useless as doubling on the bishop's pawn merely allows you to develop your rook early on that open file. It does become more complicated if the knight isnt already out and sometimes hinders the bishop but if you are already looking to trade those pieces then you are better off than your opponent at the time anyways. Your pawns werent forced to be doubled you could have just moved your queen or bishop to protect your knight. If your plan was to push the pawns to gain space (move 9) then it should have been done earlier but you have to watch out for the knights as they can still form attacks. Your doubled pawns also prevents your opponent from entering those spaces so really the bishop sacrifice might have been unnecessary but its still good in that your bishop was useless compared to his knight.
