Yes, I like #52. I like the idea of a path in the circle. Please submit a version with a path that starts out wider and gets smaller as it winds away, suggesting depth.
Thanks for #84 and #85. I was actually hoping for more of an adjustment in #84. Can you make the path much wider and go further into the empty space of the circle? Use more yellow for it, almost like the left side of the circle itself.
As for #85, I like the geometry of this. I think it might be a little too busy for what I am looking for. Is it possible to simplify it some?
