Being girly is not what Pinkie Pie is about, I feel like the artist has a major misconception about Pinkies personality. Rarity is the girly one. Pinkie Pie is more about fun and parties.
Pinkie is chaotic, she doesn’t care about shoes - she’d happily throw them off and jump in a mud pile if she thought it was funny. Hence her party cannons and general crazy shenanigans!
I really admire the artist’s ability to feel so much, and lay it all out there like that. Any declaration of love from this person would be sincere, I’m sure of it.
