I Don't Understand Cassiopeia's Visual Design
For starters, she's supposedly the sister of Katarina, yet they look nothing at all alike. While, yes, as a redhead, Katarina would most likely have fairer skin than Cassiopeia, that doesn't explain why Cass has one of the best tans in the game. Did she stay in Shurima for a weeks after getting cursed for that sweet complexion? Which brings me to my second point.
While she was getting that oh so perfect tan, because you know, beauty goals, did she decide to immerse herself in Shuriman culture? That would explain all the gold she's wearing, and that headdress. She's supposed to be a Noxian champion, and currently in Universe, is back in Noxus, but you wouldn't know that unless you read her lore.
Thirdly, wasn't she cursed, and had her beauty taken away or something? Part of her character is the loss of her beauty, yet she looks better than half the people I know. All that happened was she got a tail, slit pupils, and decided to start wearing green eye liner. Instead of having her wear claw jewelry, give her actual claws like in her Siren skin. Give her a forked tongue, or hair that's been withered or something. You don't have to make her look like Freddy Krueger, but at least something so she isn't just "girl with a snake tail".
