Sombra: His height is on par with Luna. As one would expect any tyrannical ruler of an enslaved empire to have, he’s sufficiently covered in scars and carries a chipped horn from rebellious slaves, the occasional assassin, and frequent knocks at the door by the Canterlot princesses. A minute to relax was nonexistent during his rule.
Celestia: My favorite design. A lot of you have asked if those are scales on her cheeks and the bridge of her muzzle, and yes, they are! Short feather rounds similar to scapular feathers on birds, to be more exact. There are also longer feathers on the nape of her neck. I chose to give Celly a slightly more bird-like appearance which ties in to her pegasus genes.
Luna: Glittering wings (oh how pretty c: ) and of course a much smaller frame than her big sister. She has none of the feathers on her face or neck that you see on Celestia.”
