not exactly sure what's going on in the first one, but i LOVE it. very original. 9/10. second one is nice too, nothing too special, and not a fan of the glossy thing at the top. overall a nice, clean sig though. 8/10
Left one, Nicely done, can't see any problems with it, render is blended well, good ol' pixel stretch, hehe 9/10. Right one, pretty much the same as the first but could use a bit more depth and more sharpening 8/10. Bottom, i like it but i'm not really feeling the bg, could use some more colour, but other than that, gj 8/10.
I like both sigs, top one, very nice. 8/10 Bottom one, i dont like sigs with real people in, but this one is nicely done 7/10
