Entry #3- I like this design mainly because I think it has the versatility to use it with the leaf on or off without changing the meaning it conveys. I would like to see the alternate idea of this design with the leaf left off. Entry #2, leaf and cross designs inside yin/yang may be a little too small/plain in scope of whole picture but I still like it. Entry #4, wasn't as fond of as I was the others though it wasn't terrible by any means, maybe a little too much white/blank space between cross and circle.
