I read your manga, and after seeing how much potential you had with how well you draw, I had to write my review. Now you are free to take this as criticism or ignore it but I'll leave this here either way.
1) The pacing is not good, even within the first 15 chapters, it was so rushed at the beginning and then suddenly it slowed down and then suddenly rushed again, giving readers no time to understand the world or the characters in it, this continues in the later chapters too.
2) The "chibi" or funny expressions and joke DONOT work in a situation that is supposed to be serious and scary, I had a hard time understanding which direction you wanted to take the story in.
Personally, I feel if you can decide on what genre you want the story to belong in, what sort of environment you want to create in readers mind and what/who exactly you want the protagonist to be, your work would be lot more excellent than it is, because as of now? The art is amazing, brilliant even but the story is very lacking, it takes a long while for readers to understand the protagonist's actual personality and even then it lacks complexity, the pacing is all over the place, way too many questions are left to be answered at the later chapter which is ok but they just aren't explained to the point that the wait would feel worth it.
As I have read more, I have come to realise that there is no end to plot holes, world building is sh#t, characters lack a proper personality, and more plot holes, maybe I was biased before because the art is so good but the story is terrible, absolutely terrible.
