Very nice, as usual. However Ayeka's hair seems to be off balance, pushed further back on her right, and growing longer on the left, where it appears to hang further forward. I think you could have done a better job with her torso, and the position and proportions of her right hand.
Fay could also be showing more curve, with her canonical figure. For Urd and Ayeka, see my comment on the definition of the lips in the Sakaki Close-up. As a Sith with her very pale skin tone, Raven may actually be using make-up to minimize the presence of her lips, to be giving a disturbing or misleading effect.
For people who've been observing my critiques, these are at the request of ZiemosPendric.
Thanks It was a challenge working on this one. I was thinking more that Raven is a Sith, Ayeka a Jedi (of course ) Urd a Corporate Sector agent, and Faye a enigmatic Bounty Hunter. But that's just my guess considering there is no back story.
