Ew, the multiply burns my eyes :X . Never use 2 focals in a signature, I know you might prefer it, but it takes the point out of a "focal" point. You don't know which render to look at, the chaos or the shadow one. The flow doesn't match well or even support the chaos render, and this sig will look way more better without chaos raping 1/4 of the sig. The effects are too simple, would it not hurt to try some C4Ds out or grunge brushes (I know you have Photoshop CS2, but really CS4 is the best for sig making).
