hmmm, IMO, I think that the effects around the render itself are awesome. The background is a bit plain. try adding more to the background.
You've got a bunch of conflicting flows in here. The effects actually on top of Lightening look nice, but that huge C4D coming out of the left corner isn't doing anything -- it's actually subtracting from the focal point because it's so dark. Those hot pink lines aren't doing much for you either. Overall, there's just a lot wrong with this sig. Look up some flow and C4D tutorials.
