I say low originality, but that's only because the same shape was used everywhere. I find, however, that this is one of the few fractals I've encountered with a truly 3D appearance based on BOTH blur and size of elements. I like how the dots (though obviously noise) add a layer of depth along with the spiral that appears to be doing downward. Most 3D fractals utilize solid faces for shape, but I love how your spirals carry the 3D effect despite their smooth, non-cohesive gradients. The depth is found in all of the spirals, though in the smaller ones (those other than the large pink spiral), the larger spirals appear as outlines, sorta like beveled edging, and the littler ones then form stairways.
For originality, I would like to see some other elements added - perhaps towers coming up towards the viewer to emphasize the depth of the image. Draw it out / bring out / emphasize the depth aspect.
