Got very close to the win this time - 12th place out of 10,000

Played extremely tight all tournament and used all the advice that had been given to me so far by forum members commenting on my hand histories and giving me advice - So lets me just say Thanks to all of you for your help and support so far

The hand I went out on is shown below:

Started the hand with around 23 Big Blinds, fealt like I had to get it in as 1st place pays 5 times as much as 2nd and now seemed like it was a good time to accumulate some chips for the final table. 

Let me know what you think, if I should of folded once I was 3-bet? Although once I 4-bet I was committing myself. Dont really like the idea of flat calling for 1/4 of my stack out of position also.
