Sorry but the skin was available for a few minutes, so I only took a couple photos to draw her
(Check out my pic in the fanart corner If you want *nudge nudge* ) Mercury deleted the skin in minutes because aparently it was an error that they released her. But aparently she should be available next week.
I'm not sure about her feline form changing, but I think the color of her back part was different so probably it changes the color scheme in transformation.
