Revan, he may be my mortal enemy (I am Darth Nihilus.) but really, she is so stupid if she thinks she will beat him. If she makes one fatal move by only using one hand to hold the lightsaber, Revan can kill her easily, he could disarm with one lightsaber and stab with the other. OR he could just stop her lightsaber from moving with one of his and then deal the final blow with the other.
I don't think that's really supposed to be Meetra. If you read the books and lore, Meetra (the Exile) was his closest companion during the Mandalorian Wars. Honestly, every time I look at this, she reminds me of Atris.
The intense moment of life and death to come is captured perfectly.
And the bit-dark evironment only adds to the moment. Shading is good and the background stays as a background.
The fact that you have detailed the torso elements of the neetly done outfits and some-what blurred the other parts makes it feel as if they are dancing the final death dance in the heat of the moment.
