Yo solace you gotta work on your lightning and depth son cause you got the basics. Not trying to steal your shine or anything but heres some things that can help you improve.
You got the flow well done, its from the down left to the upper right. You gotta create a focal point, this being your C4D. A focal point is easiest and workst best in the middle, so thats what were gonna do here.
Try to maybe blacken up upleft and downright sides, so the focal point will be more in the middle which makes it more standing out. You can use big black softbrushes or go make a new layer -> image, apply image. This will give you a layer with the work you got so far in one.
Use filter -> Render -> lightning effects and play around with the circle thing to match your flow.
Create lightning by using big soft brushes with black and white.
Now for the depth part, use sharpen and blur. For instance, apply another layer and gaussion blur some like 0,4. Then erase the blur on your focal point so it stands out more. Then apply a layer and sharpen the whole thing up, but erase everything BUT your focal point. Play around with opacity and erase parts you dont like.
Create a border by making a new layer, CTRL+a -> edit -> stroke. Delete the sides with your rectangular marquee tool so you only have a border on the top and bottom.
To make your colors less dull and more outstanding, there are millions of ways to achieve that. A simple one is making a gradient map black and white and put it on hard light.
Also, adjustment layers like levels and curves help you do the same thing.
Adding some photofilters or other gradient maps on softlight will create better coloring. Oh and text is one of the hardest things to do right, but you'll learn in time and i have no time to explain lol.
This is what i got after messing around very fast:

Remember that GFX is about alot more things then just that one cool effect, you gotta get everything right. Hope you dont get pissed at me for taking your stuff or being a wise-ass, im just trying to help you get better.
I can send you the PSD if you want.
