BioWare Recruiting Mass Effect 2 Models

The guys over at Split-Screen noticed that BioWare's casting director has been busy recruiting models for various female characters in Mass Effect 2. Apparently only women who are "beautiful", "attractive", and "desirable" need apply:
1. Pira: 20 to 25 years/Mixed or Exotic ethnicity. The model needs to be beautiful, interesting and unique, ideally a racial hybrid. Lithe, slender and graceful.

2. Andrea: 30 to 40 years/Caucasian/European. The model needs to be beautiful but tough, hard, wiry, slim but muscular. This is a character who can command with her eyes. Great bone structure and eyes.

3. Lian: 18 to 24 years/Chinese (will consider any Asian heritage). The role is for a young lithe Chinese character with attitude. Archetypes include Ziyi Zhang.

4. Kathryn: 30 to 50 years/Caucasian. The role is for an intense, attractive woman with character. Hair and eye color not relevant. Clear skin, excellent bone structure. The character communicates power in her eyes and her attitude.

5. Natasha: 18 to 25 years/Caucasian/European. The model will be the face of a beautiful, desirable, alluring, sexy character, who is at the same time smart, sophisticated, and in perfect control. The model should be a curvy Playboy-type, lingerie or swimsuit model - we need the face that goes with this body type.
Commander Shepard love interests, I suppose.
