Which image?

Bethany and I took a trip almost 4 years ago that lasted 6 months and we hit about 12 countries in Asia, Australia, and New Zealand! We shot over 100,000 images on the trip and finally are JUST NOW! getting around to working on them and maybe even making some huge canvas prints for our walls...
We're having a super hard time deciding which image to choose of these three! We have many other photos for sure chosen but this one is a toss up... what do you think!? The canvas will be a 24"x36"...
Thanks!
