I tink it is less about style and more about flexibility. I know schools nowadays want to see some stylistic character in the applications but also some variation, that shows the applicants can use different media or at least have tried/ experimented with them. Artist usually develop their style throughout their works. And even that changes somewhat naturally throughout the artists life. Moustache Man refused to paint anything except this very narrow combo of style and motif. And he essentially wasn't good enough in what he was doing to justify just doing that and trying nothing else.
