Nice one
Wow, the designs of the characters, the scenery, and everything are really unique. The animation is amazing too, the movements are realistic, the shots are really clever, and it must have taken a loong time to do some all that. I'm not so sure I like the music in the background so much but that's probably just my opinion, and also some sound effects would help a lot. The only other real criticism is that I was thinking while watching it 'Wow, this is good, but what is going on??'. So there's a river in the sky? The city is on that huge boat? And it gets attacked? And I'm still not sure where and what those red lantern type things on chains are. But anyway, I'm sure it will be cleared up in future chapters. I look forward to see them!
