ihave to agree with browncoat, the flow is all over the place. This doesnt mean the sig doesnt look good though. its actually great. i think that you do need to work on the depth a little more, as well as your lighting. try to blur the c4d's more and more as they go back/forward to keep the focus on your render. also i think that your lighting could have been a little better if you added a soft brush over where your lighting is (with a dropped opacity though).
