Well, it's quite similar to Harry Potter. I gotta say. You also weren't very descriptive with what a demon looked like, or what type of demon they were. Also, you weren't descriptive of your definition of a Shaman as a writer. A few grammatical errors and awkward phrasing, but I'm sure you'll find that yourself upon further revision ^^

Criticisms out of the way, now the fun part, all the stuff I liked!

I loved that you describe the emotion behind the eyes of each person, it gave a good hold and how the reader should feel about them, that was done well. Also, I can understand why you could miss an error or two, it's quite long, which is brilliant in my opinion. I like the development of characters, although the main character could be developed better. But I suppose all that will come with time, eh? I'll be subscribing and reading the next chapters, I'd love to see more come from this story. Keep writing, it appears you have a knack. ^^
