#2 & #3 I like the helicopter/gears/etc but not the yellow. If you could incorporate the logo with different shades of blue into the sunrise idea. I would like to see that.
I like the layout in Ranking #1 but prefer the colors used in #2. Try the layout #1 with logo colors from #2 and lettering in black and/or dark blue. Could you try it with 3D lettering as well? Maybe a smaller font size similar to your #1 Entry.
Entry #13 looks very professional. If you could tip the logo so it looks more like it is flying. Maybe like Entry #11 with out the city and border but keep the detail within the logo. Keep all the text the same as Entry #13.
