I like the color of #4. could you try putting a small puddle of water underneath "Best Car Wash in Buckhead"? Also, feel free to take a creative license and try out some different ideas- I like your work.
I like #5's concept alot try bringing the water up a little more around the word car wash and around the "Best Car wash in Buckhead" almost as if that part is in the puddle.
I really like #15 much better. Can you try to make things alittle crisper. I need this to be on Tshirts and signs so I just need everything to "pop" alittle more. Try darker outlines or stronger blues and see what you get but so much better I really really like it
