Thanks. I've used negatives from this session for the individual LL prints I posted previously. These are the first ones where I use different colored backgrounds. I'm not sure how I think about the different colors, though. When I'm trying something new, I tend to go overboard, before I scale it back to something that works for me.
As nudes go, you are on to something new (to me), I would rather not look at the same view mirrored but a few subtle variations in the quad might be explored.
