Wow, the first signature is amazing. About the second one; I think I like the colored one better. But they both look good.
i would go with the top for the first, and bottom for the second. But it dont matter too much, one has your name, one dont... one is in colour one aint. while that does matter, i think both tags look great.
if you brightened up the second one it would be quite nice indeed. however, the first is just too messy
