Riot, the new Star Guardian Lux skin is fantastic because...
FACIAL CONSISTENCY! I mean, the skin itself from an aesthetic and thematic point of view is also spot on, but let's be real here: you guys NAILED it here on the facial consistency on Lux. If you look at Lux's default skin (and commando skin), Lux's facial proportions and facial structure is the EXACT same as those on her new Star Guardian skin. That's great because it's showing that she's the same champion despite being in a different theme, costume, etc.

I'm not 100% sure if this was intentional, but it definitely makes the skin just THAT much better and I hope you do this with the vast majority with all your other skins. I mean, sometimes I understand if a champion's facial structure and physical appearance needs to change to match certain skin themes (ex: Warring Kingdoms Tryndamere, etc.), but some of the skins - while good aesthetically - fail to be consistent in champion facial structure such as Headhunter Caitlyn and Woad Scout Quinn:

But looking at the positive side, some other skins you guys have also kept the facial consistency really well too:

But the Lux facial consistency for her new Star Guardian skin is really great and I know that both me and the rest of the community really appreciate this new artistic direction of maintaining each champion's unique facial proportions! :3
