Another signature, seems like I can't come up with anything new.

I agree with you, the effects do get ugly. I don't want to sound harsh but I want to be honest.
I would read more tutorials and find a new style because this one really isn't working.
The splatter is too much and doesn't flow with the render.
Your render is stretched too; hold shift and drag from the corner to keep the detail in the render.
You need to work on C4D placement, lighting and backgrounds that flow with the render. Or using stocks as backgrounds.

I agree, keep reading some tuts.
