sorry I couldn't comment earlier, but wow. I'm pretty intrigued. I've only read the prologue so far (I don't have much time to read it all now) but it was very gripping.
I'm not much of a critic, but I have a few thoughts. Also people, have probably already said this, so sorry if I repeat a few things.
You added a lot of descriptions to your story. they were good descriptions, but they were mostly using sight and sound. If you wanted to add variety, you could replace some with descriptions of the smells, the textures and the temperatures. Make it feel like you're there, not just watching it. the only other thing I can think of was it was a bit drawn out. I think shortening it a small bit will add to the intrigue and mystery.
I really liked it though, and again I'm not very good at giving solid advice. I hope you continue to work on it.
