Those are incredible, especially the second one! Ok, the camera operator fluffs it slightly where she slides herself into the deep mud pool (should have been angled just a few degrees lower) but other than that minor glitch it's a stone cold masterpiece!
I gather this is some kind of organised activity somewhere (in the Netherlands?) I wonder if it would be possible to hire the venue for a day and spend it shooting lots of models in lots of different types of outfit all tackling it one after the other?
Thanks @ABGamma for posting those - fantastic work!
