Ratity? She's a rat now? No matter, we need artwork of that this instant.
Jokes aside, I love the shiny quality of the fabric here.And Rarity's hair, beautiful shading and tones in her mane and tail. Great use of shading overall. Well done! And you could always use one of the lines from Art of the Dress. Like "Stitch by stitch, snip by snip", or "Stitching it together", or something.
