That's great: pretty well mapped (maybe the eyes could be a little smaller, and you could work on the bottom portion to get the full mask), shading/mapping is excellent and it simply looks awesome. Not much more I can say, other then that I really like the meticulous attention to the little details of the reference pic. Want to see the finished product, keep going.

The sides of the area around the nose are too dark. It makes it look flat there. Brighten it up a bit like in the reference pic.

Otherwise it's going pretty well. As previously stated, the eyes need a little adjusting.

Yes, I am currently working on hood and eyes.
Also I am making it for request and I was told to make it dark.
Anyway, thanks for comment ^^
Hope, I won't dissapoint anyone.

Small update on hood.
+Fixed eyes a bit

*geez, on flatten image it looks like a bitch D:*

Its extremely nice,however it would look great if you were to darken everything exept the face.It wont look so copy-paste-ish if you do that.
8/10

EDIT:Looks great ^^ now...

it needs more depth under the hood at the sides.

Yes, I know.
I will add shadows, when will finish the hood.
Also are eyes ok now?

yes they seem to be fine as they are.

Em... Can you explain it more concretic?
I know, that opinions are important, but at least few advises are more welcomed.

could you provide some pics from straght at the front/back/side and some other viewpoints than just the front left.
