i really like it except for whatever is going on on the right side

It's a bit sharp, the colour is a bit too strong IMO, and the masks (they look like masks) are overdone in places.

I think its a bit oversharpend. I like the text.
Could I have the stock?

I think you need to find a new technique for coloring your sigs without using just a single Hue/Saturation adjustment layer. Its really amateur (no offense to you at all but it is) and doesn't do your sig justice at all.

It also looks oversharpened like the others said. If you sharpened it that much because you felt it was still too blurry, then that means it's low quality and you need to find a new render. Try to steer clear from "flat" or "2-dimensional" renders.
