This is absolutely gorgeous. <3!

Duuuuude. This looks difficult. And awesome.

wow...awesome stuff!

I really like how detailed it is very realistic.

I want this in my living room!

I love how you define the planes so well amongst the skin and facial structures layering the skull, but I would say that skin and muscle is a lot thinner than what you conveyed it. You may already know it, but my teacher had drilled me during class about it for Facial Expressions and Anatomy classes, so I bear repetition to her haranguing me.

Your skull though is exquisite, it's a fantastic core. Pretty interesting how drastically different faces are formed from shifts in skull structure!

woah. i squinted at it for a while unsure if it was a sculpture, painting or digital painting! impressive! the textures and shapes make for some wonderful depth, light and shadow that looks like a painted portrait.
