entry #6 I like the big flower, but the yellow letters of the slogan are not easy to read from a distance or from a moving car, try different colors, I like dark blue and red or blue and orange (lets see if it is easier to read than yellow) and maybe a different font of the slogan
#9 - I like the colors very much, but the font of the slogan is not well readable from a distance # 10 - mybe too much of the flowers on this one, the blue is very nice
