Nice! What I was trying to communicate in this edit is that I would like to see a little more separation between rays. It looks like where the shorter rays are it is completely filled in. I like the length of the long rays from the darker orange of the sun and I like the length of the short rays that seem to make a lighter orange colored monochromatic ring around the spiral. I think that lighter orange band could be eliminated and that every other long ray could be reduced in length to half the length. I'll make a quick sketch...
