That'd be Sweetie Belle. Genderflipped, the name is debated. I prefer Silver Bell because it pertains to music, but some fans like Sweepy bell better. Go figure.
It's from the fanfic On a Cross and Arrow. The author didn't invent the genderflipped Mane 6, but more like popularized it more than it likely already was.
It looks like good to me. How you can say this is shitty ?
He looks so cute
