I like the colors in entry #2, however, I would like something different done with the company name. Maybe it would look better if the logo was to the left of the name. not sure about the font either.
I would like for you to work on #13. I like the contrast of the background, however, I think that maybe we should make it like an oval. So that when we put it on a t-shirt or a sign, the whole back doesn't have to be black.
