Fine-Art Nudes in BW & Colour (NSFW)

I was looking over some photos of a model posed on a box in the studio I took a few years ago and I realised there were some great shots that I had not processed yet.
I tried something a little different here and started playing around with the colours.
I am not quite sure whether I prefer the black and white to the colour but both are pretty striking.

What do you think?
