Looks like some stuff that came with the windows 2000 series.
My opinion, they're all bad, no offence. To start with, the signatures are just a font, bevelled at I would say 10%, with a shadow or maybe a darker duplicate layer of the first text layer.
That looks better, not my taste though.More like this?
I don't really like the font period...What do you think about this?:
EDIT: Might remove the shadow on "Graphics Artist"
Terrible. The (if it is) drop shadow is way off and the whole K doesn't fit well with the logo background. Sorry.
It's alright, thanks for the feedback! Like I said, this is my first "signature" and my first "logo", which I truly suck with both of them
