The best ive done with c4d i think

It has nice 3D text surrounded by an abstract effect. It also has some nice lighting on it. Overall a good piece

Colours don't work well together, overall the lighting is not enough and the piece seems overly dark. You could spread the effects all the way around the canvas too, as the negative black space is a little overkill. The 3d text is alright, but again, the colour doesn't really suit the effects.

Looking very good man!

Am loving your background.

Just the 3D words are too faded and the bloom effect on the left is too much.

That's what I feel.

i like it. could use a few adjustments tho

Quite nice. I think it would stand out alot better if you rendered it out onto a transparent background and put some other color behind it. I've learned black isn't the best color for glows and flares.
