I like where you have begun with #9 and #8. I like the warm feeling of it being a sunrise or flower. However, It might be too flowery. Would you be able to play with the circular image rising, making it look more like a ying yang symbol?
#7 is the least favorite since it looks like a flower, but I am open to the potential of it morphing into a ying yang symbol. Please play as much as you can with my feedback in mind. I'd love to see what you come up with.
