Artist's description:

Princess Celestia
.
I didn’t realize how much she looked like Daybreaker until after.. this is my sun version of celestia. I have another idea of a “sky” celestia with more blue and cloud themed..
.
She has a bright mane, which causes ponies to have a hard time looking at her, similar to looking into a fire. Manageable sometimes, but sometimes it is too much. Her own eyes have adapted with a “sunglasses” type film over them, allowing her to manage the flame and even look straight at the sun as she raises it. However, she is blind in darkness, just like looking through tinted windows or sunglasses in the dark. The darker it is, the harder to see.
She also has burns on the ends of her wings, flank, and by her hooves. Over the many years, the flame slowly have began wearing down on her cost.
