Face is good, though the neck is somewhat thick and short. The lightsaber however rather looks meh. It does not have szraight symmetrical lines, which gives it a feeling of being made by an amateur engineer from junk and trash. Also, this is not Anakin's lightsaber, which is why i shall add an other sin to this pic.
I think the issue with the lips (this applies to the rest of the picture as well) is how they don't quite blend in. You should try and focus more on how to shade and make smoother overlaps. It is a little harder with ink, but not impossible.
This is really, really good! And I actually think the lips are done realistically, seeing as it's a desert planet with not much water, her lips -would- look a little out of place. My only complaint? Not Mara Jade. (JK please don't kill me)
