I'm a bit confused by the rejection as well, for the simple fact that I've submitted quite a few designs on asphalt, including Battle Fungale which woot printed, using the same exact shirt template that appears in the composition for this one, without ever having a problem.
For the heck of it, I'm going to send the art director Barbara an email explaining as such.
In regards to the design looking rushed,I assure you, this design took me the better part of 12 hours to put together. I went back in forth with illustrating the drawing with sketchy lines, then more precise lines, and the final result feel somewhere in the middle, which could explain some of the more jagged lines seen in the piece.
I love doing what I do, and the support you guys show me every week is more than enough to keep me going here at woot, so I'll certainly be resubmitting this one with some changes, as well as a second design I've been working on for this contest. Please keep an eye out for it, and if you voted for it previously, I'd be most appreciative of your continued support.
Thanks again guys.
