Driving me insane

[DNel928]

I'm pretty new to photography and even more so to post processing. I've ran across a few photos that have peaked my interest, and have tried to replicate their effects to no avail. I'm not interested in copying this style, as I have my own, but not knowing how it's done is killing me. Hope to find some clues. Overall a very talented photographer in my opinion.
