You're not being a pain. I'll have your updated sig to you shortly. When you say darker, what colors specifically would you like in the background?
EDIT: I almost forgot to ask this, would you still like to have TP Ganondorf? And, would you like a .png image or a .jpg image? .png is a image where the images pop outside of the background...if you need an example of what I'm talking about, just look at my signature. .jpg is just pictures that are seen with everything that is showing, so, for example, if I were to cut off Link's head in the picture by moving the render around, you wouldn't be able to see it at all when the pictured is finalized.
