I actually have been veering away from text for a while now. I dont like the look of any text anymore.
I would have to agree, but it does seem plain over on the right... perhaps some tech brushes like this? deviantART: where ART meets application! you can make it barely noticeable, but it will add a bit more to the sig, not to mention I think it would fit with the theme.
you are very welcome, only thing left is i think you should maybe duplicate the render layer, do some blurring or smudgeing, then lower it behind the original it would look better imo
