For the Love Competition, this is the female to the Royal | Magical couple.
I imagine that her eyes/gem can glow different colors. Red is for destructive magic (which is why the grass is dying in her footsteps), green is for restorative magic. I imagine that there are probably other colors, too, but that's the only ones I thought through.
On her other hip, the pentagram is black.
I hope she wins! I had a lot of fun with her design.
