sorry i couldnt see it before its working now,yeh u got some real good depth in there which looks great, however ur focal is kinda messed and the lighting, coz the halo guy all nice and looks preety lol the effects next to him look the same, i guess its the c4d so maybe create a focal near it so it dont all look to blended or sutmhing..i ont knwif u knw what i mean.
This looks pretty tight.. The thing that twitches me is that the Halo dude has a lonely blue color to it that I don't see in any other part of this sig.. In this case.. Your blend is off track by a tad tiny bit.. If you can just add the color to the corner or somewhere else around.. I will love it fully.. :]
Add a deep emerald photofilter on 80% density and a B&W gradient map on linear dodge at 10% and it'll look much much better.
