ok, here is my entry. Turned out to be more labor intensive than i thought but i really like the result. I have tried to really innovate with an original mark and build in a 3d aspect. feedback welcome.
This really awesome and creative. Actually, it is too awesome. I love it, but it is over the top for my site. The swoosh as an airplane trail is great. The big brackets around the 4 have wonderful depth. It's just too much. Can you try toning it down?
