bottom is best. if the top had color and u added some light in certain places ita be real nice, but gj
I like it, but not the gradient map (?) over it which dulls the sig. I think if you took that out and added some depth, it could be really nice.
Second has too much topaz looks a bit boring. Not that much to look at either. For a black and white sig its a tad dull. Imo its "just another sig," nothing special.
