Nice wrinkles
It looks genuinely disgusting. In this case that's a good thing, though... so, points.
It looks like my grandmother, if my grandmother died her hair green... and had eyeballs the size of apples. :U
Overall, the hair on the right side of the head is great, but the hair on the left looks "meh" or bland for some reason. Probably because it's just a lot of simple straight lines.
The mouth is really good. Probably the best part here. I wish I could draw mouths like that.
Definitely freaky, very freaky. Good job.
