I'm not a fan of the jawline you have on there.

The Hair Looks good..
How to make it? Use what?
The eye too, Its nice.. Shading are good there..
What the heck is that Black thing? Under the Month? I dont like it yet..
But the effect at Right month and the Nose are nice.. 7/10 <Because the Black Thing under the Month (Not to Like it)>

You should have not made the teeth mirrored. Also they look pretty flimsy, make them thicker.

lol, i dont like the tooth..
it looks mirorred.. and the nose is too big..
Make it more small..
Still a WIP?

Teeth looks very curvy, and bad.
The eyes look like it doesn't focus to 1 point, make it right at the middle.

Inside the mouth: Really sucks, it's like you mirrored everything up. Try to be mire careful next time.

The others are good, I'd like to see the outcome of this.

7/10

I like it!
But the nose its just a bit too big and the teeth are looking c/ped and strange :|

My First Skeleton head : /
CnC please

Wow!
This is your first one?
It's really really really nicely done!
It looks so cool, but it just has a seam in the middle but all the rest is looking awesome!

It looks like a x-ray print xD

Yeah my First, Thanks
Just Fixed the Nose and make it Bigger
