Also, I don't trust Sin'dorei... they get along with my Succubus far too well." Drachos, Undead Warlock.
Now, I love this bit of work, the art style and the post fit well with what you (or at least what I) would expect out of the Sin'dorei Elite, and the detail on the eyes and hair is absolutely stunning. I am not sure about the stomach of the character however. The shadowing makes it seem like she either has a nasty scar, a little bit of belly (not that that is a bad thing, but its VERY unusual on a Sin'dorei) with a slight more obvious dints there then normal, or maybe a early sign of being pregenant.
A very early sign.
If we had a second pose with this, it would be easier to figure out what you intended, and its not exactly a flaw, hard to tell what was intended due to the pose.
However I love the armor in the background, the earings and what she is wearing. It shows her she is in a more safe haven at the moment, either Silvermoon, or her own house, and its something we see very little of the Sin'dorei... well other then in eroctia. In a time when the Sin'dorei are always fighting one person or another, its nice to see of them actually posing for a painting in a place of safety.
A part of me thinks I am over analyzing what you attempted with the piece (seeing things that aren't intended, like an English Student looking for hidden meanings in a book), and thus sound like a wanky idiot, but regardless, I love this picture.
Theres something off about the philtrum area... Maybe its the nostrils being to narrow? Well besides that everything is great. Pose and facial expression are especially eye catching. Nice work! thanks for the share.
