thanks for all these comments!
I`m really glad!
This is my newest sig!
You must be registered for see images
What do you think?
depth is a bit bad you should use Filter > Render > Lighting Effects on the center so it would become better
here's an advice, don't rely on placing the render in the center of the sig, it makes the sig sometimes pretty lame and typical
work more on blending, duplicate the render more often so you can stain it and rely on alternative layers, also the colors of the sig don't blend, make a new layer, use apply image on it, set a gradient to the applied image, then set it to overlay or soft light, you can lower it's opacity to come up with better colors, and try to give a better placement for the C4Ds
good try though
