A great story so far, quite original with a premise you don’t see too often. The story is picking up steam, so all I can say is that the beginning is great and having read the Author’s other HP fanfic I have full trust in them to deliver an amazing story.
Writing quality is good. There are some grammar mistakes, but nothing so bad that it becomes unbearable.
Updating stability is… stable. it’s actually crazy to me that this is 1 ch/day, with such good quality and great length.
I don’t have much to comment on story development. It is moving at a steady pace, but the story is still in its beginning so I dont have much to say.
As for character and world design, this is a fanfic so I don’t have much to comment on.
Overall, an amazing beginning and most likely an amazing story in the making!
