That's exactly what I was looking for, thank you for actually telling me how to improve!

Illustrated wrote I want to give criticism, without being too harsh. Everybody else covored that for me.

This is not clean at all. Clean implies, well, looking clean. Sharp, professional.
This is packed with stuff. It's cluttered, and there's a lot going on.

I do like the blue/green color scheme. But the green lines over the text makes it harder to see.
There is also just way too much going on behind the text. I would take some of that out.

I don't know what the giant thing behind the text is, but it's too way too bright, and the texture on it is very low quality.
You should darken that a bit, or maybe choose a different material or change the projection settings on the object.

And Cinema 4D isn't just for text floating in space.
I'd suggest tying to make a scene around it. A 3D room, or fiel or mountain.
3D text doesn't belong on a 2D canvas.

sums it up right there yeah its pretty bad im not gonna lie
