Avatar Element - Head

I'm finding it quite difficult to create an avatar because I still don't understand where half the buttons are!

Here's the first stages where I'm currently modeling the head first so it gives me enough time to make it perfect. I have modeled some of the body but I'm just posting the head part.

Using front and side pictures I have constructed some sort of a base model to sculpt later on.

Here's my progress so far with my logo element...

I have done several other pages of ideas but i thought i would post one to show where I'm at.
