"Silent Ponyville:The Dark Descent" Revamp

Readers, I plan on rewriting what I have released on "Silent Ponyville: The Dark Descent" (I will shorten it to "SP:TDD" in blogs, comments and author notes). I have been getting advice from other writers and I wanted to release the best work I possibly could. However, due to this, I needed to change the story somewhat. Just the protagonists backstory, and what was released so far. That's it, that is the only changes I'm making (the stallion won't be nameless anymore and he will be more fleshed out as the story begins, but the changing of settings will stay the same). I'm new at writing like this, so want to do the best I can; but I would appreciate any feedback (as long as it is productive) you can give. I'm trying to figure out how I'm going to sort this out, but I hope I do so I can get back to writing. Again, I would love to hear some feedback (or suggestions) you have, so leave them in the comments of this blog or in the story as soon as I upload the chapter I'm working on. I'll try to get it out as soon as possible, so I'll see you all there!
