OK, it is too dark, way too dark, you need some light in there. The render is really hard to make out, I still can't figure it out now.
IMO if you make a popout sig you need a render that is whole and pop it out top and bottom, they just look odd when it only comes out one side of the sig. I actually like the text, but think it needs a different font, I would suggest soething like Tahoma.
Having said all that, for a fourth sig it is very good, and it's great that you're not worried about trying newer, more difficult things like popouts. Keep it up.
