Love the inclusion of pictures, helps set the scene. I feel there could be a bit more world building, in my opinion. Why do I feel that the buckle is important? Anyone else? Just me, alright. (Is this helpful at all?)

Don't know how much help I can be since you already fixed most of the obvious problems. The pacing seems to be better (ish), Fluttershy had new living quarters I am going to assume it is carousel boutique considering that she is sharing with Rarity from what I can infer and if she is why not write the name? Regardless of my nitpicks on the story has improved pacing, improved the grammar from the previous though providing some geographical landmarks might be nice to get an idea on where they are living.

This is better. They are getting a bit of ground rule set up or at the very least mentioned. Like the backstory for Anon. Though he should ask the basic questions when ya get Isekai'd. "Where am I?, What are you folks, Do you know what I am? Is there food.. (Ok maybe not that one) Things like that. Also the pacing is good. Also please don't follow the trope of Rainbow Dash wanting to attack the hummy on sight. At least not without a reason.

Good chapter, the images help with the inmersión of the fic.

He seems to be taking everything a bit TOO well here.
