Honestly? I pictured Shortcake as a person who'd feel threatened by better artists, but it seems she's aware that a lot of people dislike her art and is trying to improve, at least on that aspect, so if people grew a spine and told her "dude this looks bad here's how you could improve it" instead of taking her designs and run with them I think the designs would at least be decent. It honestly feels like she has ideas but doesn't go over them again. That's almost the first thing they tell you in art-related careers: expect feedback and if you don't get it, ask for it.
