Nice update. I think overall your sculpt is a bit lumpy. The mouth and nose especially. Looking at reference shots on Google, these areas (nose&mouth) are surprisingly smooth.
The ear seems to be too low in the head. Looking at images, perhaps placing it higher, and maybe slightly smaller? Though I imagine this varies. Also the connecting area between the bottom of the eyes and the top of the nose needs to be flatter.Give it less of a ridge.
Anyway, cool stuff so far.

"Earth? Earth-with-nuclear-weapons Earth?"
