As a Jhin Main, I personally think that the Dark Cosmic Jhin skin is the least fitting skin for Jhin. I would like to suggest you a skin idea for which I would pay 10 € instantly. My ideas for now are: His back animation=him stepping on a stage where he opens the curtains (as he often talks about stages, performances, etc.), and while he bows to the "audience" roses will be thrown at him. This skin´s overall theme should embrace the character of Jhin and his identity as The Virtuoso to whom the performance is above all. I hope you get my idea. As for the skin name one example: "Khada Jhin". Thanks for reading, have a nice day.
(I wrote this on another Riot Article that was not that likely to be read so I post it here as well.)
