Beautifully done! You know an illustration is a masterpiece when you instantly see it as a whole and no single part sticks out, looking unbalanced or out of place. ^_^ The hair, ribbons and skirts flow so well too! The only thing that could make this image have more depth would be adding more body to the boots, but that's all I really have for critique. And if Usagi had a dark side, I'm sure your design would hit home!

For me, this is something special! I grew up loving Sailor Moon and Innocence Corrupted really captures the darker side of this amazing story!

(sorry if my critique is no good ^^)

I must say that I rather enjoy this image. The image feels very symmetrical, which is good because that's a hard thing to do with yin and yang kind of pictures. As for the difference of the two Moons, I rather enjoy the color scheme you went with as it suited the yang well, as well as contrasted the yin very nicely. Something I really enjoyed was the subtle difference in their eyes, it took me a second to notice the difference really. Giving the yang a more somber and gentle look while giving the yin an active and playful was very nicely portrayed. Lastly I enjoy the background, as if a bit of icing on a cake, the yin looking like the day and the yang a starry skylight. I would say that my only problem with this image would be the title. This is mostly drawn from the thought that yin and yang isnt about corruption, but of balance which is excellently portrayed in the image. In fact ironically if you were going with that idea, the regular Sailor Moon would be the more aggressive and more "corrupted" version. However I really do enjoy this image, excellent work my friend! Truly a masterpiece.
