The boxes at the bottom were meant to be a small comic with pointy ponies, but that turned out WAY~ out of my skill level. At least within the time limit for the 10 year celebration.
Celestia, happily to Pinkie. "Oh my, Pinkie, what a lovely cake."
Celestia, despondent, as oblivious pinkie exclaims: "Oh no, that's styrofoam, steelwire, and fondant! No sane pony can eat that!"
Celestia, much happier as Pinkie continues: "That one's for Spike! Ours is still in the oven!"
Still, learned a lot about Krita's magic wand, and funny enough, layers, with this pick. Know it's super simple even for a pic of a cake, but kinda like how it turned out, honestly!
