The attempt at blending was ok, but not the best. You really need some lighting, depth, flow and to work on your text definately. Try using C4D renders in your backgrounds, then smudging/blending them in. Also, try giving the sig more depth, it's just flat, give it life. Finally, the text. You relly need to work on it! Just try use simple fonts in about 12px, make it apart of the sig though, then say, write the same thing and position it like a bit up and right of the original text in a much bigger font size at low opacity and low fill. Oh and for a border, just a nice 1px black outline would be fine...or even just a 4px line going across the top and bottom. Hope that helps.
