On my main, I am a die-hard Katarina main and enthusiast. So, naturally, I am extremely hyped about and happy with the new skin.
However, for me personally, there are definitely a few things that would make this skin go from a 10/10 to infinity/10.
Hair should be a bit more ethereal, maybe a darker color.
Daggers should not glow like lightsabers.
Other than these 2 things, I love the skin and I love the work. Keep at it.
