just a couple things from me-

the right side of the effects are actually too red, you want them to be a bit darker, creating the effect that they are in the background.

text needs work, a different font with a different color.

add a lighting source, pay attention to your render and find out where the lighting is coming from, then apply lighting

other than that, i dont see many issues, good depth and great concept, i always like the pop out sigs
