It's a matter of taste but I really like both designs, gives me a sephiroth vibe. koozek seems like you prefer the westernized designs of kingsglaive huh? ;P
They really hit the right spot for me, yeah. It's almost perfect, imo, and how I would love future mainline FFs to look like. But I admit, some of the less important characters do look a bit too generic, but I guess they are supposed to be more like "NPC"s with the main characters having more distinct designs. Nyx is already one of my absolute favorite FF designs ever.
Personally I prefer game Ravus over the movie version, simply because I think he looks less like Jamie Lannister (I just started watching GoT).
And to me he seems more interesting, less generic. I think it's the shape of his face.
For Luna I interestingly prefer the movie version, though.
Okay, I take that back a bit now that I think about it, though he doesn't look as obviously grim and evil as Ravus. What I actually meant was his personality that wasn't as clear black and white when you knew his background story, which actually had something strangely... sad and melancholic to it almost (one of the few moments that felt even remotely sincere or touching in the FFXIII-saga, imo). Now the comparison of their personality is not fair, of course, as long as we haven't played FFXV, so I'll stop and wait.
No wonder SE was such a mess. They even say here that they thought they suck. A studio from mostly Polish background has better "know how" than Japan developers which were making games since 80s. Crazy.
