THe text is borderline. If you were to lower it's opactiy and have other stuff just like that around the WHOLE sig it'd be a lot better because then it'd become almost part of the BG. However when it is just there alone by it's self and it is really distracting. The first thing i did when i saw the sig was read the words. So add it some more to everywhere, or make it smaller if you can.

The bg, it looks a bit funny.It's black around the render but then like right away it changes. and it goes to almost white in some places. It makes it pretty odd feeling. I would try to either get rid of the black or fade it in a bit more or something. Maybe even just put a clipping mask there to cover the adjustment.

Was this a stock? I can't really tell but that might be the reason for the black.

The left looks awesome, I'd liek to see more of it on the right.
Needs some work but overall, it isn't bad.
