need some ideas

Put a text, make it glow and blur, add any anything cool to it (like another pic)

put something tron-related (that is tron, i hope... ) like, the motorcycle, or the cars, or some scenery, and put that one a black background, and make the motorcycle/car/scenery about 60% opacity. you'll have a nice signature there. also, add some more flow to it. i feel like the render is totally apart from the C4d's.

ive updated it, wat u think now?

still gonna add more C4D

What she said. Your c4d's dont flow with the render or background.
