A solid character ref! This gives me a lot of insight on the character's model and details that help me visualize them well! The models themselves look great too, they all have a consistent and interesting style! However, I do think this sheet could benefit from two more things; a few more expressions and poses of the character in certain emotions, and a brief explanation of what certain pieces of the ref sheet represent. For the latter, I think this could be quite helpful with certain details such as what the purple orb on the far right of the sheet represents. And for the expressions, these could really bring the character to life even further and showcase a bit more of their personality. These could open up further creative opportunities for those who'd like to make fanart/fanimations of her, and possibly even for you as the creator.
