Cyrus
>Feels like fujo pandering, but that basically comes with making a design based around Darkrai. His face doesn't go with the outfit. Cyrus is angular, grey, sleek, logical, machine-like. Darkrai is noble, wispy, brooding, elegant. There's too much style and personality to fit Cyrus as a character. It needs some white as well, more than just his face.
Dawn
>Like she's playing dress-up. Colors work well, but the overall design screams "I am a child at a costume store" which doesn't really match Cresselia's elegance and grace.
Marnie
>Boring. Feels like it could have worked on anybody, even with the color choices and "frayed" sleeves. The apron implies cooking which severely limits the utility of the look. Basically 2022's version of Palentine's Dawn, except not as impractical.
Bea
>Apart from the short scarf, it's actually really nice. Nice colors, the shirt goes with her hair and complexion. This would be a nice outfit when going on a date during a festive season in cold weather.
