I think the animation here has a lot of potential
My only few complaints is that in some parts the art feels "traced" (Example given: 0:11, 0:33), or the faces don't feel like it matches the character, or sometimes the concepts themselves don't clash well with what some of the character designs (eg: 0:33, even though Ralsei IS in a sense supposed to look like what's currently portrayed right now, but it just doesn't feel right), But maybe that might be me.
Keep up the good work though! I know this took a lot of time to do and I know I shouldn't complain about it when animation takes a lot of time to make, but I wanted to give my opinion on how it could improve or could use some adjustments.
