Plastic Pie Rocks

The first thing that strikes me here is how you have managed to merge Faber's famous Pie plugin with Trystianity's famed Plastic script to create an incredible work of art that is naturally symmetrical. I see point symmetry( Julia symmetry, I like to call it) here, and the Pie sectioning effectively communicates itself to the Plastic structure.
The four spirals seem to obey the rules of thirds and fifths, although I would like to see a little more detail in the spirals themselves.
I really like the gradient you've used here; Ultramarine(not too bright; properly subdued), Olive, and Hazel greens make this image a winner in my opinion.
