I like how the render turned out it looks very cool,maybe reduce the opacity on that secrect effect you know

.The only other thing I would do diferently is maybe add one more layer,fill it with black and put a lensflare in the right corner and change the layer setting.It needs more light on the right and less on the left.If you did that this sig would be perfect.Your c4d usage is getting better in placement and that's something I have had a hard time with since using them.
