I think this is amazing bro. You seem to have a very good sense of lighting and depth.
I think the entire purple section(eyes included) is perfect. No changes.
The hair and the the reddish thing above the eyes could use some tweaking
and maybe add some more detail to the neck.
But the proportions are spot on, and it actually does have some creepiness going on there ;) so well done bro.
