So, as there was very little light, this is a long exposure, which explains for the very soft skin... due to her shivering! Models are the true heroes of photography. Whichever efforts the photographer undergoes, they're the ones exposing themselves to cold, to fear, to uncertainty and, eventually, to the camera and therefore to the world.
So I will never praise her enough for her amazing patience with me that night! It does take a lot of affinity with Eros... But it will in return give you a chance to cheat Thanatos! ;)
