I believe that you could work more on it and it might turn out to be a pretty decent signature. I actually like the effects on the left, but if you look at the background, it's like a little bit of effects on the left that stop too sudden and the background goes plain. I would suggest letting it all plain or changing the hue of that part of the background in order to look togather with the left part like a whole, not two different things.
Overall, except the background which I would totally change.. xD I would probably change a little the render position, but this is not that important.. And you should add more effects, but not too many, around the render, it looks pretty plain and you can see the low qualitiness of it around the edges.
