That is some serious wizardry! I love your dodge/burn work; fighting with deep shadows, especially in natural light, is a huge challenge for me. I spend most of my time and effort trying to get things into the workable dynamic range of my sensor.
With the original at my disposal it becomes really apparent how much time you've sunk into reducing the deep contrast that the environment gave you. It's really neat to see! I usually end up with a dozen pieces of white stuff snuck into various spaces out of frame to try and kill those.
