Hello, We like the connecting dots on entry #2. (we like this entry the best of the four) The bar connecting the O's on example #4 looks OK but not as good as the dots in #2. Entry #5 doesn't as nice of coloring as the other entries. The darker blue color isn't as appealing. The offset of the word 'spoters' doesn't fit with the name. Example #6 looks OK but really doesn't speak to hotspots. Perhaps you can integrate something into the buildings linking them up or add wireless bars somehow. The bar connecting the O's on the bottom takes away from the buildings on top. The top of the T cutting off in both words makes the letters appear like J's. Overall we like the colors. Please let us know if you need additional feedback. Thanks!
