Those swirls are hot, but I'm not really feeling them in this style. Id like to see the same swirls used in an anime sig, with not as much detailing in the background. At the moment, it feels like the whole focal is opened up, and spread across the sig. About the text, im not to fond of the reflection in black, and the white being 2d. Feels like the perspective is warped. One more thing, I dont think a lightsource would do anything but detract from the sig, it would just feel so out of place and isolated. I think no lighting is needed in this.
