Rate the signature above you.

You need to moce the text some closer to the focal.
I can see some flow.... but I want to see some more colors.
I don;t like the c4d around the text

It's way to big for a sig in my opinion. And because of it being so big, it kinda gives me an empty feeling. But it's not just that. I would use more effects; use c4d or some more nice brushes. Also, your bg is nice, but try using a stock. If you do, you can start playing more with depth, lighting, ect.

Keep working, the results will follow.

it's pretty descent, there's some sort of flow and the lightning fits well.

The inside is great, but I hate that large white border.

Very nice! Can't really say much bad about it. Great colours, depth, effects. Also nice render. Might go searching for that myself.
Though the only thing I would change is the text size.
It distracts just a bit too much in my opinion, but other then that, great work!

9/10 nice depth and goodl placement of the text

The b & w works well but it seems like you only threw in some C4d's randomly. The fog is good but the blend of the render could be better. Text needs some changes.
