Ugh, suffering from creativity block. To try and break it I used some random generators at Seventh Sanctum (
http://www.seventhsanctum.com/) and Serendipity (
http://nine.frenchboys.net/index.php) and got some things like:
The promiscuous, worldwise female half-Basilisk necromancer. She has a voluptuous build. Her non-human ancestry gives her a horribly inhuman appearance.
The clever, sheltered female half-Air Elemental illusionist. Her wardrobe is severe. She appears far more non-human than human.
The tactless male half-Gorgon alchemist with a large fortune. He body is one half human - one half taking after his non-human ancestor.

This wise lady has large eyes the color of coffee with cream. Her luxurious, curly, amber hair is worn in a style that reminds you of a dustball. She is short and has an angular build. Her skin is pale. She has a wide forehead and a large mouth. Her wardrobe is mysterious.
This noble man has narrow eyes the color of smoke. His fine, curly, slate-gray hair is medium-length and is worn in an exotic, carefully-crafted style. He has a feminine build. His skin is cream-colored. He has knobby ears. His wardrobe is practical and businesslike, with a lot of yellow.
A little mixing and matching, and I doodled these two.

A half basilisk necromancer with amber hair and mysterious(?) clothing.
A half air-elemental with dark curly hair and severe clothing - I don't know what would count as severe clothing, I stopped here.
Didn't start the half-gorgon male.
About 2 hrs each, I'm slow. I doubt I'll go any further with them, but I think I can say I'm comfortable with faces. Not sure if the creativity block is broken yet.
As a side note, the random generators on these pages could also be used for a contest / activity here at Pixelation.
