I'd have to agree with iNs@nE, that's exactly what it is. Thanks for sharing though.
I'd defnitly make the text more clear, let it stand out of the image with drop shadow and what-ever other effects your interested in. Lastly, I don't like the backround at all. Try more colours, also more effects (but don't get me wrong, clean signatures rule too).
I'm bad at giving critique.
