Asymmetrical Work

This a recently-completed asymmetrical mandala.  As it is, there is a sense of balance to it as well as some symmetry.  

I love the color choices, spontaneous as they were, and the mix of shapes and their placement in this piece. Together, they combine in a way that plays with depth too.  It was such a delight to watch evolve!

Using three shapes (quadrilateral, circle and triangle), how would you design a round mandala?
