I like what you have done with the lighting in this sig. The light to dark is very cool. I think that the clipping masks are a little bit much... they make the focal a bit hard to distinguish on the right side. The text is too small, but is in a good font and is well placed. Basically, the only problem is that the clipping masks make the right side too cluttered. Very good work, as always.
I really like this sig, the blending i very well done but like the others have said there are alittle too many splat clipping masks. Try to either get rid of them or smudge and blur them to more depth to the sig but other then that great job dude.
