Would be really epic if everything wasn't so choppy. x_x The circles have some sort of strange distortion, and the vector isn't rendered so nicely. I'd like to see some wireframe C4D's in here, too. But I like the style. Work on it. ;D
The effect is great. I don't like the little black ang grey orbs in the background. Other than that, great job.
The circular things don't look like perfectly drawn circles. I wonder if that was intended O.o. Anyways, nice sig. And i like the red glow stuff around the woman's neck.
