I haven't rated a signature in a while because I've been doing other things. But I'm up-ing my standards now. Not only signatures but art in general. This signature is rubbish.
Not the best text placement. The effects make the text look like its disappearing and that's something you don't typically want to do, a better font for the text might appeal more too. The border is disgusting, I don't recommend borders but if you do make one, I recommend making it 1 or 2 pixels from the edge of the signature going inward and having it be a sold color eg. black or something.
Overall, the signature is too overly sharpened, has zero flow, and has no lighting.
I don't have the materials I used to have in GIMP because my old computer broke down. I had to get a new one. Besides, this is my first signature in a very long time. I don't mind you telling what is good or bad about my artwork. But just saying it stinks like that I don't really need. And do you really think IKY's signature was much better? Because the majority of others I've shown this to thought it was amazing. Thank you for your comment. But I'm tired of constructive criticizm. You all might think it is a good way to learn but I believe it is a good way to discourage the artist.
