@TZero After reading your message i just felt in a bed of feathers and thought "aww" 

When a peice is so good, you don't even vote for your own peice in the challenge :(

Beautiful work!

@Eggy Yes, a trident. Yeah, i think the same with the sky

It's the sky. It's so dithered that I personally find it kinda distracting. But the siren and her hair is excellent 

Also, while I'm at it, I have a curious question. What's that thing that impales the siren? Is it a trident or...?

@Eggy I would apreciate a LOT if you could tell me where you see the most. 

I love these kind of feedback, it helps me more than "lovely piece", but still like both.

@ philippejugnet What do you refer with the 3D?, maybe the deepness, it's difficult to me to see the noise, i asked for help, but no one reply 

Personally, I find so much dithering to be unnecessary and noisy, but other than that, it's not bad 

Looks good and it's indeed a nice idea, but I wonder if it wouldn't look better 3D-wise not this much 2D-wise.
It's rare for me to say this, but I believe it needs more rendering, the picture is overall noisy. You could've managed to make some clusters to make it easier for you.
very well done tho, a great improvement over your past works ;) (It's a good thing).
