I like them both. On the first i like everything but i dont like the rectangle thats off colored on the far right. Id think it would look better if it where just black. And where the white smuding/brushing ends on the right, to me it looks like it where cut off. Like your where brushing on the corner and then centered it(if that makes any sense.) You'll see where i mean below.

And the second one i dont see really anything wrong w/ it. Its cool ive seen the first style sig before but nothing like this one. Nice job.
