Nice work on all 4 designs. I like #15 but there's not enough color. #11 is good but too many cartoon characters. #14, not enough color and bad mascot. #12. Not enough color. Too military.
I really like #20. Could you please work on the color scheme a bit? The hammer is a good idea and I like how you used it in #19. I would also like to see the "FAST, FRIENDLY AND AFFORDABLE". pop out more. Thanks very much for you're help... Arthur
