Mhm. The text is okay, I don't see anything wrong with this sig.
Although you could add probably a 1px black border all around it.=D
A border always finishes a sig.
Good work, KIU.

This is pretty decent but I'd lose the text,
Lighting is nice and so are the effects imo. kiu.

Your background needs contrast! The c4d you used is well blended and the lighting is pretty decent, but besides that, work on blending the render into the sig in non-focal areas. keep it up!

I agree with most of what has been stated above. I like the flow of it personally. But with all the effects you have going on, I would suggest working on sorting out the depth a bit more.

[silent_assasin]

I recommend making the focal a bit less lighter and sharper. Also the text isn't great, i dont think this works without text. But nice work Kiu!

[Pulse III]

Its lacking some depth imo.
