Well, her front legs are bent a bit more human-like, but it is fine, as their proportions are correct, and are more or less the same as the artist uses in his gallery (for example: mykegreywolf.deviantart.com/ar… ). Although Luna's composition is a bit human-like, it is ok this way as it looks more "natural".What is a bit missplaced is luna's horn, it should have been like Celestia's.Colors and shadows are great, especially the used in Celestia's hair and their crowns and hooves.
