Thanks man! Faces are definitely tricky as hell - if you don't decisively nail them, even a great model can be completely thrown off by a weird lookin' mug.
Noted on the horn color. These are just place-holder colors for the moment, but I'm keeping notes for when I actually get to the textures. I know a lot of people end up doing the lion's share of their albedo work with with baked polypaint, but I learned modeling through handpainting method so I tend to wait till post-highpoly to tackle textures.
And EEESH! I gotta tweak the darkened eye sockets/eye shadow - she looks like a demonic owl when zoomed out in those shots.
