C&C

Pros:
Good color scheme.
Some of the clipping masks look pretty nice and add to the warm, mystical feel of the sig.

Cons:
Stylistically speaking, this sig style is relatively cliche.
There doesn't seem to really be a focal point.
Too much going on.

This sig could have been a pretty great looking one had you taken out some of the extra "froth", softened the tones, and blurred a lot of the artifacts.

The left and right extremities are a bit too overwhelming, and [especially on the right hand side] do not really blend well with the rest of your sigs.

Remember, the focal point is the heart of the sig, it's what you want to pop out. Unfortunately, I could not locate one.

Try sharpening your render next time...That seems to work for many.

Also, practice blending your render so as to make a seam transition, (not pixel wise, but flow wise)....

Anyways, I'm done with my ranting, and I hope to see some more of your work.

Thanks,
CS out.

it wasn't a render, it was a stock but thx before the comment
