Of your entries, my preference is probably #8 although I think I prefer the font in others - I like seeing Cities in lower case not upper case. Not sure if its a bit too colourful. Not sure what else to tell you write now - I think I need to see more entries to help me get ideas for feedback on all. Thx!
I also like #14 with the 18 cities all together at the bottom but don't like the curved lines (are they clouds?). I also do like the one you did with the 18 in the cirlce (#12)
another thought - maybe just one of those curved lines rather than two - and could we try the buildings with less lights/windows so its a little less busy looking (maybe something more abstract) Thx
