So i logged onto the LoL PBE now (Test realm if you didn't know) and i noticed that a bunch of champions had their classic skin *ART* redone (Teemo, Mundo, Twisted Faith, Jax, Amumu, Pantheon, Renekton.) If i post em all it would take up alot of space and i cba making them smaller :P But here is so ya get the idea. (They look awesome.)
*Edit* seems like they updates some of the purchasable skin arts aswell (Full metal pantheon, Myrmidon pantheon etc)
Mundo:
