I love it aswell. Text ain't that great, but you're not the only one having problems with that. *whistles*
Well, for the text you could move it up, and closer to the center. Leaving it a basic white would compliment with the rest of the white, and would give it more meaning. But, seeing as this is a delicate looking signature(the child gives me that idea), you may want to use a less-bold font.
