Thank you @brookeloving! Quick answer to the location: they were all taken in the Drakensberg mountains region of South Africa (one of my favourite places for photography, and only a 2 hour drive from where I live). You can have a quick read about the area on Wikipedia here: https://en.wikipedia.org/wiki/Drakensberg
In terms of how...well, thats a bit of a longer explanation, but as promised, I'm working on a "behind the scenes" guide :)
Dude. What a gift. Thank you. If I'm ever in South Africa, I will have to remember to check out the Drakensberg Mountains!
