As I think I said a while ago, Yin Release has to do with illusion and non-physical creation. Yin Release can create things that resemble reality, or manipulate that which already exists, hence why Shikamaru can manipulate shadows, Sasuke could make his Chidori more powerful, and the 2nd Mizukage could create vivid illusury constructs. The things Yin Release creates will not have real form without the input of Yang Release; without Yang input, the illusury 'imaginary'genjutsu will stay an illusion.
