I like the top one if you made the background. Don't make the chick stand out more. Its good as is. Dont use such a small and sharp font. Use a font thats a little more fun to match the rest of the sig, but dont go overboard with some crazy font :blink:

The second one is ok but the glow/blur look it has really kills it. That and the dotted line thing and your name. Change the font, and get rid of the dotted line. Just put the text in a place where its easy to read, but not in the way. I can see it fitting on the left side, towards the bottom where its all white if you made the text black.
