I was lucky that i could get this close to this reptil, found it while i was in vacations at the hotel i was in Vallarta, Mexico. I Took my 6D + 50mm with extension tubes to get even closer. I wanted to give the look as a dragon with retouching so i changed a lil bit the colors to a warmer/fire tones. You can put some music from the Hobbit at the BG while watching this :D, i was inspired of Smaug for the retouch.
Here you can see the process of the retouching:
