Let's remember one thing. You're in control of this story and no one else. Second rule, you're in control of this story and no one else. You've got a pretty good story so far if you don't let canon rule you. Looks like you goint to let you and I hope that you don't.
Now that's a curious review. If you're referring to the first real fight scene and my lowering of the gore factor a bit, I trust my betas who come from a wide variety of interests and experiences. Their thoughts had a lot of merit, and after quite a bit of back-and-forth, I made the compromises. Now, if you're referring to the canon bit, that's another question entirely. You'll find two major bits of canon present in Echoes. First, there are horcruxes. No hunts, however, for them. Second, there is an eventual HG pairing. However, as neither of these characters is as done in canon, I tend to view that as I-the-author-like-redheads, and not something particular canon-like. As for the rest of canon, well, the characters are similar, but their experiences and bindings are all different. Some bits will be like an echo of canon, and some bits will be completely different. With the AU pretext, it's simply not possible for Hagrid, say, to be a fundamentally different person -- his life experiences built him before Harry was an issue. People at or near Harry's age have the most changes, and thus the most freedom to change. This, of course, is a choice that I made at the outset - to change what the pretext dictates should change, but not change those things that it shouldn't.
