Love the colors. Especially like the contrast between the orange sun in the bg, and the green/blue color gradient on the 'swooshes', could you please make the 1 'swoosh' underneath it the same color?
The idea of something coming out of the middle of the sun like #11 is a good one. We just need to find the right something, the fort top is a great idea but would like to see something else (wind turbine?).
