The long-needed sister image to
this. Celestia resting within the sphere of the sun, but as an Alp instead for some reason. You can consider this to be the form she takes when she goes to visit her other, littler ponies.
I should also point out that this image hints at part of my headcanon universe within which ponies are included - in the center of the Sun floats the island of Athens, watching over the world of Epona from far above.
