Well as its my first animated sig i was focused mainly on the animation so threw together a randow BG and just used a font.
if that animation was on a more detailed bg, then it would be a 10/10, but now its a 9.5/10, and that is still great
yeh the bg is only render>clouds, then that extrude thingy, maybe if you did a little more to it, like some brushes, it would look great
