i like the designs, but i think there can be some changes (personal opinion).
i think valyra is perfect, no changes there. with nodin, there is a massive resemblance to teisel... i do believe is hard to seperate 'anime-esk' character because of a lack of many facial features that the style comes with but also narrowing it down to a legends theme can also cause limitations. i think maybe if you gave him a 'robotic' nose or jaw and changing his hair can make a load of differance. Sirocco is ok, but she seems too overshadowed and kinda bland. i think since she was original planned to have long hair with some fringes, maybe you guys should look into Layers hair design from MMX.
