Beautiful colours here. Great decision to include the high clouds, helps fill up the sky and reflect the sunlight in a great way and give it the feeling of a cool, clear summer morning. Nice take on Celestia's mane, good rendering of the metallic nature of her regalia (particularly that mantle) as well as its gems, and I just love the reflective shine and vibrancy of her yees, as well as that small, very Celestia smile and head shape. Oh, and the wings look nice when folded or held somewhat down like this. Well-shaded, too. Great job!
