More clear one, I guess.
The black dots on the left are revealed by the glow, I think a fade outwards would work quite nicely.
I like the blur on the c4ds, but needs more at the bottom, it makes your focal point stand out more.
More random dots on the right, and a c4d sticking out of nowhere, if you decide to use the fade out then you should fade this side as well.
Oh yeah, the yellow border isn't very good for sigs like these, a 3-5 black pixel line across the top and bottom would be better, imo.

The other pred - still don't know what you did exactly, I don't know wether or not it's your fault or the render's, but there's a fair amount of noise on his mask and a bit in other places, you should really paint over/something that would blend it in, and is that white+black curve on his right arm an effect? it isn't really subtle, and I don't think the background fits in all that well... it looks like it's made out of neon lights.

*Is that 2nd sig a predator? no idea why I mistook it for one yesterday, must of been tired.
