I'm no expert as I have not done GFX in over a year; nonetheless I think the Orange/Red C4D does not mix with the Black and White background.
Let's see.. The flow is pretty nice. The signature could need some more depth and "something" in the background since the bg does not look very interesting for now. You could add some lighting to improve the focal point and maybe darken the place around the render to create a nice feeling for this tag.
Whored render but good effort with the effects. The gray scale background ruins the color for me, and some text would help, but you have a good WIP.
