Very well-written first chapter, I'll give you that. Aesthetic-wise, though. This could definitely use more description to give us a broader picture of their surroundings, but I understand what you're going for if you want to leave it up to our own imaginations for clarity.

I like the intro chapter. I agree with Hivemind, though, it'd be nice to see how the rest of Equestria has changed and picture more than just a line at a warehouse-turned-party bar. Great dialogue too, eagerly waiting chapter two.

Well, I have to get the business with Fluttershy concluded first. But rest assured that the next few chapters after chapter 2 will be more slice of life before we get to the trouble.

Other than that, thanks! I'll certainly try to put in more details.

On another note, my blog contains some more details on this AU I've cooked up.
