The janky 3d movement of MYM really needs a lot of work to make it look good (check out the Opaline song). They didn’t put the work into Allura, and being a feline that should be graceful and sleek, they payed the price of it looking bad and unbelievable. There was one frame I saw where they had her lift all four paws off the ground while slowly walking, it was bad.
This, though, is smooth as silk and very flowing. Top marks to TYT for the work. She also looks significantly less like someone’s furry OC they just had to get into the show.
