Hey, Bo, have you thought of filling the white space to the right with more math. I'm no graphic designer. But What if you took a zoom in on one of the petals; and wrote a legend for each colour. Just to fill the white space to the right?
All that white space is a garden that needs to be filled with Leau Petals!
