I don't really have a "rating" for your sigs but I do have some advice.
Most sig artist make a background, some layers of editing, and then paste the render on top of it. Some colour filters to make it match with the background, and done.
I think it would look much better if you "merge" the signature and the render. Put some layers of effects on top of the render too, so it looks as if the render is "in" the signature, and not on top of it. Look at my own signature to see what I mean.
I'm sorry if I sound like a know-it-all right now QQ
