Glory to Princess Celestia, bringer of day and light! Let her dawn shine out across the land, and let all know the might of the ruler of the day!
Awesome job here! You did a great job positioning Celestia - this is a nice dramatic pose we would never see in the show, but is still quite believable. I like how her tail wraps around in front of her - it provides a nice contrast to the bright light at the top of the piece.
The shading is well done, the light even more so. The way her horn nearly disappears into the glow is great, as is how the light turns her mane gold at the top. This is a great piece, and I like it a lot!
