Oh yeah... you still don't have ending 2 (I think that's Route 3 in the walkthrough?). You should be able to get the other CG as well if you manage to get that route.
I believe that one should be the 'lore' ending which focuses a lil' more on their myth. It also somewhat has a more serious tone. You'll see :)
(Honestly, it's also meant to be played last. I personally consider it as the canon route)
