I'm only a beginner in Chess, but I would have made a change to moves 15 - 17. 

Although a Knight may look like a more versatile piece in a game of chess, I would favor a Rook anytime. So instead of 16... Rxc3, I would've played, Nxc3. Whether the opponent decides to lose a Rook for a Knight is totally up to the opposition, but either way, you have more end-game piece set. 

Like I said, I'm only a beginner but that is what I probably would've done. 

i think is game is good example of when not to play h6

white would have very good postion after 4. e4?!

better is Nf6 right away Bg5 is not a huge threat
