Nice blending, the render is too small in my opinion, so isn't much of a focal. Looks boring due to the large empty space which doesn't really work unless you have lighting comming from that area, or the flow is hitting off in that area. Lighting in this piece is kind of an offput in my opinion. The text currently is a distraction point, i would try put it near a focal. Over there it doesn't compliment your signature at all. No real depth in this piece. In my opinion the render needs sharpening up. A possible C4D ontop of this on colour dodge would look nice.
