I think Jane and Bella look great, especially because they seem to complement each other. Some sort of thorn-type thing might make Bella more poison-like, but Jane definitely seems right for a normal-type leader.

For Layla, I really like the dress color and the candle. Are the colors inspired by the Umbra Crest? Also, I kind of like the tiara, but I'm not entirely sure what to think of the pink at her waist. Is that a common article in some culture?
