The way you designed it makes it feel choppy and I dislike that. On the positive it feels real like computer matrix style.
I feel the main render has very little definition because the little boxes seem to take it away from it, i think there should be less boxes and the render needs something to stand out, maybe a little contrast or burning around the edges. The sig is overall kinda strange in the meaning I'm not sure what I really think of it, I think it is very small and a little crowded, but if that's your style then that's your style, Hope my C'n'C helps Dan.
