Princess Celestia is gorgeous, with only a few small flaws.
She has a dull black mark on her nose, which I have tried to remove without success. I suspect it is on the inside of her plastic. She also has a small black mark on her left ear, but this too seems to be in her plastic and could be a factory flaw. There is a small mark to her right rump, this could potentially be improved. The glitter to her wings is lovely, with only a little bit of glitter loss to the ends. The glitter above her eyes is also lovely with only minimal loss in places. There is only a little bit of glitter loss to the tip of her horn, and very slightly to areas of her wings.
Her eyes are lovely, as is her symbol with only very minimal paint wear. Her mane and tail are gorgeous, just a bit dry towards the ends.
