Love #10... Is that kryptonite crystals at the bottom of the globe? :-) How about if we remove the kryptonite and move the top of the lettering into the blue circle maybe at the diameter and give a white outline to the letters when they are in the blue at the top. Make the font a bit thicker. Maybe keep the 85 and the north the same size as the 85 currently is. Maybe move the star to 85 degrees ie; at 1 o'clock on the globe?
Maybe try one design with the swirly lines being 3 thin lines out of the star to the lettering 8 o and h.
Thank you for the feedback. The idea of #10 was an abstract polar scene - the white angled shapes is breaking up ice, the curving shapes are the Northern Lights, and the Pole Star. #51 & #52 - variations according to your suggestions.
