I'm very much liking these tags. Very nice use of C4Ds for spicing up the background and adding some sexy lighting.
On this tag I, again, like the way you used C4Ds in the background to incorporate the lighting. They go well with the focal as well, but I feel that the render stands out a bit too much, make sense? There also isn't much depth in it, as compared to this tag, but that's already been said so ;
I really do like your style, I just think maybe you could add some effects in front of your focal so that it doesn't look like it's just standing in front of a(very well made) background. Can't wait to see what else you come up with so please update often. :'D
