These are a great start... Can you add a hippie man like in #5 and #9 but with a beard? Can you add a sun in the background? I like the thick bubble (font) letters in #2 but the solid letters in #6. "the Taco" is ok but it needs to be bigger and the STOP needs to be bigger / bolder too. Please remove the burrito and nacho in the stop sign. It just needs to say The TACO STOP inside the sign and nothing else. Also, just one flower is better than two. I like the straight flower better than the curved one. Take a look at some of the other designs and see if you can do some of the things that look good in those.
Thanks!!
general comments: #5 and #9 has the best hippie man, but he definitely needs to have a beard... #9 has the best STOP sign! We like the font used on 'the Taco' in the STOP sign in #7 but it could be bigger and more readable. #8 has nice looking letters at the bottom on 'Tacos Burritos Nachos' but the words should all be aligned instead of 'Nachos' being at the bottom. The words in #9 are good the way they are curved, but straight looks good too, as long as they are big enough to read. The grass in #9 is great. Please feel free to use more colors and detail in the sun or sky and the sun should be high in the sky like the stop sign. I uploaded another picture (see sun1.png) to let you see as a reference to how to use more colors in the sun.
