PORTRAIT SERIES: Initial Concept

My first initial concept is looking at the dynamics of a toxic, intense love between two people. I would have a male with long hair and a female with long black hair. I want to set it outside, firstly, because, for my single portrait project, I decided to shoot in a studio where it was fairly easy to achieve the correct exposure, therefore, I would like to challenge myself by trying to shoot in natural light. Secondly, because I envisage the couple together in touch with nature in a grassy field or by a stream in a forest. I know a place in mind which has all of these different nature forms - Farnham Park. The aesthetics I want to create involve making the people look extremely cold, with blotchy cold purple/blue skin. As in the photos below, the people look emasculated, vulnerable, delicate and weak. 

As for one of the images of the couple, I was thinking of a shot like this, which symbolises how they are intertwined with each other, blinded and entangled together. Visually, I think this image is stunning, with the cold icy colours contrasting with the darkness of the hair. Also with the fact that they are both naked, therefore in their most helpless, vulnerable, exposed states. 

Here is a link to my pinterest board which explores my concept for the portrait series through images which either aesthetically or symbolically portray in a way that is relevant to my concept:
