Future Mask (WIP)

[Xenon02]

Well hello there !

I've decided to do another project with this mask (The background will be later I want to focus first on the mask) I've spend like 5-6 h on design and I'm struggling with the his vision  on the front. I wanted to make it go deeper (some kind of a 3d effect) I'll appreciate of any kind of advice !

The concept is cool,but it looks flat;you should make it rounder with better shading(make it darker on the edges if light is coming from the front, and add highlights).Also the four circles on the cheeks have all the same rotation:you should make the inner ones rounder and the other two thinner(same for the eyes).
