Mysterious start, where did Leiyu come from, what is her goal, who is she searching for...
Pros: I love the way you colored you story, it fades with the background, but the thing is that if you don't stay consistent with this style, in the future chapters, readers could think that you're just trying out things.
I liked how wanted to point out who the main characters will be, but I feel like it was too pushy (and obvious)
One last thing here is that, you integrated the "origins" of Leiyu really well, it really filled the dialogue there, at the campfire.
Cons: I don't really like that you made (almost four) chapters just for meeting (and getting to know better) the princes-.... (I won't give away the spoiler for those who didn't read until that part), I think you could have done much more for those three chapters.
I didn't like how you used a bit too much effects in chapter two, simple is better, trust me.
I saw that you changed your way of drawing a little bit, you wanted to use more things, just to test some stuff out, it's okay in my opinion, I test things out too in my drawing sometimes, but the sudden changes can make some upset faces between the readers.
The absence of the pacing is a huge problem in your story (but I still liked reading it), you should add a little bit of more action (not James Bond type of action, more like "The hangovers" type of action, the pacing that happens way to quick is a small problem, but the small pacing is a huge problem.
One last thing here that bothered me a little bit was the amount of chapters that were used for the "origins" part, one or maximum two should have been enough, four entire chapters is a high risk for you, that the readers will just skip by it, and we do not want that.
Observations: I just want to point out I have no deal with the drawing whatsoever, this is my opinion as a critique, I only write ;(. If anything, please contradict me, if I mentioned something wrong. :3
