I have some serious pony drawing season right now~ Im probably gonna make whole mane six in this style, i really enjoy drawing this~. Pinkie's goddamn mane is the hardest thing in this world to shade, i swear.
Those quieter moments of Pinkie's are way adorable. Not the creeper ones, but the ones where she's less overly energetic and shows her more thoughtful side. Those colour layers in Pinkie's hair are impressive. You managed to properly shape her hair with those shifting tones. And those shifting shades of pink and purple on her, too; the left front leg is properly shaded for looking naturally in that pose, and so is the left rear one. And the thin yet lovely eyelashes, and the expressive ears, and the bright irises... I, for one, find it quite beautiful. Even if you used the same "magic/nebula" pattern as in Twi's picture, it's still nice here.
