Agreed on above, and its a bit overly messy... fix that... and make the render match the colours better I think... but was said in above post already... but nice try... kiu
Firstly im going to have to say something bad.
Stop trying to do over the top effects with so much color until you learn the basics first.
You may become a good artist but atm you seem content on just trying to make weird color patterns with c4d.
[Blend]
Very poor. The render doesn't actually blend in any way I think removing the render would have made the signature look better as a freestyle abstract signature.
[Depth]
Very poor. There isn't really any depth to your signature. And with so many c4d that dont blend it actually makes any depth you had be hidden.
[Text]
Here is a good tip I teach most beginners
Create your signature with no text. Then once you have created your signature copy merge or use new layer image apply. And then right your text and use your copy of the final signature as a clipping mask. This will normally always make the text match the signature as you are using the signature it self as the color basis.
Overall.
Stop and restart.
And try to practice the basics before your attempt the higher grade effects.
