She does have those crags on her original Riot model though. I guess to make them look a bit more "ancient"? See http://www.lolking.net/models/?champion=131&skin=0 I guess from her Lore the Moon cult has been wiped out entirely and that's basically old leftovers. Might be magic infused and all that or even be made of…
@AlexKola - Fuller lips, check. Might make her look a bit younger too I guess? I scrounged up her a forehead a bit, I think that's what you mean by roughness. I'll just smooth that out. Googling "confidently sad" :). @BBFirefly - I think I had her likeness down a bit more, earlier in the sculpting. But it got lost…
