big problem with the picture,you scaled it down in a way which makes the picture look squished and improperly proportioned and you should blend her in a bit more.The backround isnt bad,but i would suggest to stay away from the random unorganized abstract type sigs.The text isnt good,at all.That font doesnt fit in with the sig,and its just..there.No effects or nothing.I think the drop shadow is a little too far from the actual text,and i dont think you should really ever use a drop shadow.

hope this helps =)
