I just watched the entire video. It was amazing. I loved, most of all, the slow motion you showed in the ocean and waves. I'm sure you have much more footage, since you have only covered two areas in this film. Loved the music choices, the editing, and the slow cinematic flights. The opening reveals were also beautiful.
I've been to all of these places, but in good weather. We did a circumnavigation counter clockwise of the entire island, including Skogafoss, Dyrholaey, Reynisfjara Beach, Black Sand Beach, BVIK, Reynidranger, etc. Feel free to write me on a private conversation for link to my Iceland video ( I don't want to hijack your thread).
