This one was a lot of fun.
I like them, very stylish.
On the first one, though, the eyes are way too big. To the point of being stylized..
And I think you should darken it up a bit. And probably spend more time on the mouth more.
I dunno, you'd get more comments in the self portrait thread for the month.
My hand hurts.
