This is apparently the 3 upcoming skins for Arbiter.  Left to right is Lumaya's Prophet, then Jade Serpent, then Darkfallen.  The last one will be in clan shop, while the first 2 are purchase only

Are any of those better than her original look, you think?

I think some of them have the potential to look pretty good, though keen to see how they look in game.  For me it's also more about variety too.  Really interested in seeing how they take on other champions

I am 100% here for Vampire Arbi. 

Also wonder if in game Avatars will have the reskins too.
