Nice effect, but it's a little too contrasted this time. Ever tried adding some gaussian blur instead of the regular blur? Or, you could increase the blur transform's weight. Try that, and you'll notice how the contrast between the various "worms" gradually fades. It'd be better that way, in my opinion.
I mean that the borders are too neat and defined, and the lights from the center of the spheres are a little too harsh for the eye to view. Or, you could try switching gradients. Just if you want though, since you're the one who made that fractal and, as such, it's you who decides in the end.
