Yet another comic with good eye-catching art. Your use of colors and composition really pop, especially with sceneries and more surreal shots.
I'm not sure how much of this is helpful versus just a personal taste thing, so have your grain of salt ready.
What is this story about?
After reading everything available so far, I have no idea. The two girls at the beginning don't seem relevant to the most recent episode, and neither does the massive world history stuff. I assume the themes the girls discussed in the first episode -- the concept of evil, understanding that everyone has their own reasons for doing things, justice and punishment... -- will come back later, but so far I don't see any themes stringing all of these scenes together.
Even if you have plans to link everything together eventually, it's dangerous to spend too many pages before you provide at least some hints that yes, everything that's happened is relevant to the story as a whole. I feel like you have a good story with thought-provoking themes. It's just a matter of putting the individual elements together in a way that catches a reader's attention and holds it to the end. To be honest, this is something I've been struggling with myself in my own comic, so I understand how difficult it can be. Just don't overestimate the patience of the average reader. 
Infodump
Most people will tell you to skip the infodump about the history of the world, the war of the gods, the forgotten era, etc etc. I... am one of those people. XD Your infodump episodes are beautifully illustrated, but for readers like me, that's not enough to hold my attention. I tend to just glance at the pictures and not read the text at all with scenes like those. And if that goes on for too long, beautiful art isn't enough to keep me there at all; I click my way out of the comic.
Is there any way to pepper the story with this info, instead of dumping it all at once? Like have the story with the two characters in the Yellow Shark going for a few episodes, put in some infodump interlude, resume story, put in interlude, rinse and repeat? That could become an interesting and powerful way of telling a story, especially if there are any parallels or opposites between the story episodes and the infodump interlude episodes. But without knowing how the rest of the story is going to unfold, I don't know if that's applicable to your story at all.
Speech bubbles
Why are they so tall? I'd suggest making them wide enough to accommodate at least one normal length word, such as "understand." And please, no more bubbles that

Names
It might help if you tweak the dialogue to name the two characters ASAP. Sometimes people forget character names and just call them "the blond," "the tall guy," etc... But providing names is one way of signifying that yes, these characters are important (on the flipside, many writers actively avoid revealing the names of throwaway characters because they don't want them to seem important). Since right now, I'm having the trouble of identifying the most important elements in the story, giving names may be a step in the right direction.
Hope that helps!
