This piece is excellently done. It's a nice and simple depiction of a hero and her nemesis. The poses are appropriate and convey the characters well. I would also add that the background and accompaniment are also very insightful and true to the characters' personalities and represent who they are and what they stand for in a very clear and concise way. If I really HAVE to say something critical I think the transition from one character's side to the other should have more of a gradient transition, but that's admittedly being very nit picky. Overall, this piece is very well done!
