A lot of people like the general design. Admittedly, I did too. I think my success came from keeping it simple and smooth– the motion was coherent and corresponded to every other element. The elements that people didn’t like were the motion of the smallest circle– they wanted it to be on the outside of it’s path-circle and the colors. I definitely understand the color criticism especially given that I had not put much consideration into that part of my project. I was more focused on the movement of the circles at the expense of the color consideration. As for the criticism about the placement of the circles: I tried many different combinations of which circles go inside which and had carefully considered this component. Perhaps this is just a difference of opinion.
Moving forward I will consider color more and I especially liked the suggestion to xor the colors.
