I will admit that yin and yang is the ideal example of separation and union. I feel that this fits the challenge well some may not know its meaning. I must however complain about the shot its self. It apears to me that this is a side long shot of a rippled balnket. That was put into high contrast. But I can't say for sure. I don't know if I like this or not. It is a photo and I feel it may stretch the rules a bit on the poatrait of artwork part of the rules. But will vote as if it didn't 7
