Ori Sketch Help

Hi I started on a sketch for Miss. Ori and it feels like something is missing. But what is missing? it seems so empty. She is in a room as a human, looking into a mirror and her reflection is showing her robot form. Her ball is her necklace, there will be JOIN LEAGUE TODAY or WE WANT YOU league posters. I want a picture based on her lore. I'm open to all ideas. ATM I'm not worried about perspective or proportions. I'm working on a karma sun goddess picture as well, so i'll take ideas on that one too. The brown blob on the karma picture will be a temple.
