Another creative piece here and I like the repition going on. As the sphere get`s larger though it seems to develope a bit of noise. I`m kinda guessing your using Apophysis and then a some post work on this? A way to smooth it out would have been to check the postprocess bit then after the renders finished save then increase the filter radius and save a different points. I`m hoping this makes sense and no offence is intentended on your work as I really like the image and think you`ve done a great job!
