I love the lighting and painting in general, as well as the way the lightsaber blade seems to boil; my first impression of the character, though, was that she's got really manly legs. Just thin out the thigh. But otherwise this is really fantastic; the work on the cowl is nice.
Hurrah for lightsabres. Very neat stuff, mate. Only thing I would suggest for critique at the moment is the upper thigh; it seems to be curving unnaturally, as if the bone itself was curved. (Although, this could just be an illusion due to part of the lower leg being lost in shadow.)
Otherwise, the anatomy looks good, and the rocks and lighting are very convincing.
