Dang... Mid-transformation. I love pieces like this, but this one here is a major exception. I can easily see her sorrow mixed with her fear and hatred, but it's so well portrayed, I can see how her hatred is overpowering her. Wow. Well done. Very well done. I'm gonna have to go check out your gallery sometime soon. This looks fantastic!
Her fear and sadness are really powerful, and it's really spooky how she's seemingly being engulfed by the mists. Excellent work on her pretty face, especially the contrast of her bright eye, and matching frantic pose. All of the colors are beautiful even though it's such a terrible moment.
I love the major amount of emotion added by that one tear. It's such a small detail but it shows Luna's true despair, that she never wanted to harm her sister. The dark energy inside her was beginning to consume her will.
