Kent,
Yes your designs are very professional, clean and crisp. What they are lacking is fun. The company is healthy mobile food trucks, trailers and carts. People will be looking at trucks from a distance that you want to stand out. They will be standing in line and need to see fun. I like the colorfulness of some of the other designs that makes you think of fruit, leaves, with the name boldly displayed. I do like simplicity, but it needs to be fun based on the feedback of 20-30 predominately female individuals.
I do not like the fork at the end of designs 29 & 30. I like the clarity of the design in #21 & #36.
I hope that helps! And I appreciate the designs.
