"Gwinnett" is too big. We like the 'tree' for the 'T' in #5, but the colors don't really appeal in either. Feel free to experiment with other colors than the ones we chose -- just not too wild.
We like the blue single roof. Please see how it looks also with blue letters and the single tree, as in #14. I am not sure about the balance with only the one tree, but we aren't crazy about the vegetation on 10 and 12. Thanks for all your efforts!
