On the very right, the colors don't blend whatsover, and it distracts me from the focal. It seems a bit too monotone on V1. And in my opinion, V2 and V3 have too much contrast. Lower them to about the level of contrast in your current sig I'd say. The right is the only sort of.. per say, problem with it? It has too much negative space in that one particular area. It would be way better if you'd edit the .psd and tilt the c4d you already have more to the right. Or, even find a c4d that would flow well with it and add that.
