I just absolutely love how it captures her ever so intensive and radiant beauty. However, the slight shine on her lower lip distracts the viewer, and the famous Princess Luna Curl on her forehead doesn't have enough volume. After that, if you enlarge the moon slightly, and add more detail to the ears, this portrait should be absolutely divine.
I'm not really serious about shipping in general. It fun to read about it at times depending on the characters, but otherwise I don't take it seriously. Whatever people come up with is fine and I don't mind that.
