You didn't even bother to mirror the bevel/emboss effect on the ear-covering-objects. All you have to do is reverse the angle. It'd look better if your light sources weren't all over the place, the shading seems awkward and weird.

Considering some of your earlier works, 4/10.

I didn't use that bevel/emboss effect, I'm training shading by hand. The helmet is pretty much fucked up.
I was working on face by heart, but I felt lazy and tired since I started the helmet.
Thank you for your comment. I'll try to do better next time.

Looks awesome, needs more colores tho. But I really liked it.

9/10

Does he have a metal eyepatch nailed into his skull?

Yes. Isn't it obvious?

It is, rather unexpected though.

Seeing as I could tell what it was, good job.

there would need to be shadows around the eye patch if it was nailed in, get some depth in there.

pretty boring and averagely done for your standards.
youve got highlights but no shadows/lowlights.
just isnt very much to CnC on this one, for a cartoon head it lacks character and just looks.... meh

I'll try to add more depth there. Thanks for your comment. I don't know how to "add some charackter" to it. I guess I have to find an inspiration before making a head.
