Dis. This right here is awesome. That take on Celestia's eye shape done so intricately and right, particularly considering the medium. That awesome hair, with the pretty nice decision to go for lines indicating its flow that makes it look both ethereal and normal at the same time. The rather nice work with the bodyshape, with a particular compliment for the legs and the boots (they sure turned out awesome). Them beautiful feathers and wings in general, such lovely soft shading and shaping. And that sigil of curving intricate symbols behind/around her, looks both like some sort of indication of magic and the glow of the sun. And the rather nice background, to boot, particularly the clouds.

Great job!
