That actually makes me think of Warhol's Marilyn Monroe images using consistancy and defined colour to define the image. An illustrator names Luke Weller recently came to give a talk and explained how he uses mono printing to give a rustic and rough look to what would have been a boring block colour. Maybe this is something that I could look into.
I feel that still life would be too easy to achieve because the objects and the lighting is fully adjustable however controlling a model is a lot harder especially if I am working alone because I have to get the model right and adjust the lighting to match that position all myself. I find this challenging and that's why I enjoy taking fashion and organised portraits. Initial thoughts lead to taking black and white film photographs and then using prints, ink, paint etc to manipulate the image. This could possible change the whole image entirely.
