The idea was good, but the execution is lacking. By that, I mean the effects you went for were interesting, but in the end, they just make the sig be all over the place.
The font is hard to read, the wiggles fx is not really working. The grunge textures on the right side plus the render fx makes the render look LQ.
The left side is interesting but if you want to split the sig in half, the right side should be a continuity with a different twist instead of a completely different sig.
