Well, I like it, alot. The only problem is that if you didn't specify a name, the text would be rather hard to read, unless you looked real well. Maybe enlarging the size of the text a bit would help, not much, just a little.
Yeah well, I didn't want the text to override the render and take away the strength of the siggy, you're probably on a really high resolution. Can't really do much without spoiling the siggy since I had problems just positioning the text itself.
