I'm not a specialist in fractal art but I particularly find it hard to come across "good" 3D fractals. I guess because of the third dimension and the maths that are behind it it's easier to make mistakes.
But this piece here is totally fascinating because it's also communicating with a feel of the surface. The fractal like that looks fragile but that's totally ok. It's reminding me a bit of a jewel or a part of a bracelet. The little "arms" hanging around at the top and bottom of the fractal really makes me want to explore more of the structure of this fractal! (I wish I could also see more of that part)
I think the colors blue and orange are well chosen, together making a complementary contrast. But the conrast could be more intense. The orange is almost getting lost in this picture.
Now the only thing I have to criticize is the "balloon" in the middle of the picture. It seems that due to this stretched form of the balloon a lot of texture information is getting lost and appears in a bad quality. I don't know how to fix this but if you can somehow it would make that image perfect.
Overall a real fascinating fractal that differs from other fractals by its surface feel!
