I don't think the render is good, it isn't the right quality.
The font is a standard one, ok.
I like the borders, but the sig is a bit too big fromthe standard sizes.
Overall a good attempt!!
A friend of mine bought a new car. He had it modified and took it to a car show. He gets a call from the owner of the buisness saying that 1 of his guys airbrushed the face you see in my sig ALL over his car for the show. They were pained over but i think it makes a great sig.
