ehh..
The smudging is blank, if you understand what I mean.
Its nice , but we've seen alot of smudging that looks the same.
Very nice touch on the blurring, although the snakes can be a little sharper.
Knowing your a big person that speaks about the lighting of a signature, your lighting isn't to pretty
I really hate the little scales/c4d/whatever it is at the bottom of the sig.
other than that , love it
edite : I also just noticed you have duplicated the render , that's not to PURTY either , should have used a motion blur on the render under the main one.
