Use some gradients and stuff to add more white to the BG. Color with gradient maps and b/c layers. Lighting is key to this sig.
The little bit of lighting in V3 makes it a lot better. Just add something else to the bg and this could be perfect.
Looks better. What you need to do is go to the half gradient, set it to white, select the circle shaped one, and just gradient it right behind the render. That would look good.
It is getting better man, v4 is probably the best one, but it still needs some more details to it IMO.
