6 min BTS of Ylva in the cave (Patreon)

Here is a BTS (behind the scenes) of shooting Ylva in the cave. It also gives you a slightly better idea of what's going on: The cave is not slim and narrow, but the next hill on the right makes it look like it when you move into the cave and look the other way.

The moral of this is that you have never really seen a location before seeing it from all places. Sometimes moving your position just a few feet, right/left, or up/down can radically change the possibilities of a location.
