Dr. Vahlen is the Chief Scientist assigned to the XCOM project. She leads the Research Team's efforts with great enthusiasm, as her particular interests lie in finding ways to adapt the alien technology to advance human scientific developments. You can read more about her here: http://xcom.wikia.com/wiki/Dr._Vahlen.
She is posed with the intention of being somewhat neutral/passive, but depending on how you look at her, she may look slightly annoyed, as if you had just destroyed precious alien artifacts by using explosives.
Posed with XPS, model extracted from XCOM: EU game files.
Firaxis team created Vahlen, not me!
Notes:
Probably should create a base or use some sort of raft/rim sort of thing in order to get the heels to adhere to the print bed. I'll test it out when I receive my backordered Prusa i3 MK2S.
