A thing to notice about the Heavenly Queen's is that they all have their own speciality and focus in terms of the world of cosplay as a whole. As mentioned all the way back in Episode 6, Erika Awayuki is all about cosplay as an Art with extreme preciseness. Ririsa, who aims to be the perfect Lilliel definitely would aim to reach that level of accuracy. Given how well they did on the last episode, I've got no doubt they'll do great on the next two.
