Really like the style of entry #54, but not sure about the colors. Also a little worried that a gradient might make this more difficult to reproduce on various medium. Is it possible to maintain the effect without gradient colors? If not, would you be willing to play with the colors a bit? We like either color by itself, but together they're a bit too seventies. :)
Hope that makes sense, and thanks for your contribution to the contest thus far!
Cheers,
