This has a rather calm and subtly warm atmosphere to it. The lighting was done really nicely. Celestia looks lovely here, and you portrayed the tiresome emotions she's feeling really well - she's not looking forward doing all that paperwork, but she's dutifully resigned herself to it, and that's so very in-character for her. I especially like the way you depicted her face, mane, and horn. You put a lot of detail into this piece - on Celestia, the objects across her desk, the desk itself, the wall behind her... and it turned out beautifully. Really well done.
