This is great work so far. I really like the descriptions you used, they really set the mood you were trying to convey.
I was actually wondering if you wanted to join a discord that a friend of mine owns. It's for writers to share their work, get feedback, and offer tips and stuff. You can actually promote work too, if you're good enough. I think they'd be happy to have you. Here's the invite, if you want to check it out.

OMG! Flatastic! And Lancelot is a bus driver!

Flat for president :D

Shirou and Flat would be great friends.

This is simply pure GOLD!

interesting, we need to see more

I rarely laughed so hard! I love you Flat! Ah, and great job!

I can already tell there is potential in this fic. I like it when authors take liberties and place their stories in alternate universe, I think it's a perfect showcase of their creativity. I am particularly intrigued by this universe and am eager to find out more about the story.

And Flat is hilarious, though other readers may need to read up on Fate/Strange Fake for full enjoyment of his character. There's not much to comment on since the plot is only in the beginning stages, but I do feel like you captured the essence of characters like Shirou and Flat perfectly, their lines truly sounded like something they would say.

Overall, I'm interested. Looking forward to seeing how the story progresses.

You're off to a great start, keep up the work! I love the little details you put in your writing. XD I don't have the patience for that myself rofl. As far as the setting goes, it's a good way to keep mechanics but place it in an AU setting where you can use the characters you want to and make a nice story.

I'm loving the dynamic between Flat and Shirou. They are both so cute; Flat is a dork, especially when he said "They are chasing me as we speak!" Good grief, Flat. XD

Everyone seems in character to me. Great job!~
