How can I fix this head?
 

I managed to do my first head alright, (as I posted), although not proportioned correctly. Every time since when I try to create the eye part, I get funny creases that I don not know how to remove.

A pic is below.

Could someone please advise me?

I think it'll be because you haven't dragged the vertex point that comes from the corner of the eye back a little and it's too far away along the z axis from the point next to it, so it's stretching badly.

I like the noise, but i think things would be alot easier if you used refrence images. Keep it up though :)
