Ugh. I don't like it. There's too much of an op-art feel, with the background the way it is-- and I think it takes away from the design on the continents.

I want to blend all of the rings together and make either a smoother background, or a monochromatic one. Although, I'm not sure if that will be satisfying either....  A black and white version really highlights the areas of high and low contrast...
