Well done...very clean and professional. If you have a black and blue design for #15, I would like to see it as well as something that places "llc" in the logo someplace (subtly).
I see what you were going for in #62 and I appreciate the creativity. One of the things I like about the first two are their simplicity and memorability. They also represent strength with the "back to back" imagery. I'm not very artistic but it does lend itself to some symbolism. I'd also like to see some representation of our Texas roots in some other submissions if folks have ideas. Well done...thanks.
