It is great, but I think it is lacking an "wet" feeling to it. If you add a specular glossy shader, I think it will do the job ;)

Just to be clear this is not a criticism of your artwork cause honestly it looks great. The problem is this a duplicate that is based off an Andrew Price tutorial which is not allowed according to the new policy. So I am told that is the reason my work was rejected. Okay now I'm confused. The adminastrators need to further clearify their policy regarding duplicates.

A very nice render. I agree with Thomas that it needs slightly more wetness or specular.

it pretty cool...even without the "wetness"
