Okay, here is my teeny, tiny suggestion. Just a little suggestion on formatting, that's all. Nothing about the actual content of the fic:

I think it would be easier on the reader's eyes if the dialogue were double-spaced. So instead of something like this:

“Nooooo!”
“Yes.”
“No!”
“Yes.”
“Well, that certainly makes life easier. Where on earth did you find it?”
“I think you mean where on Ferrulous Prime...

It would look like this:

“Nooooo!”

“Yes.”

“No!”

“Yes.”

“Well, that certainly makes life easier. Where on earth did you find it?”

“I think you mean where on Ferrulous Prime...

And so on. It just makes it easier to read, and less like a wall of text. I looked at a few other fics for comparison, and the standard does seem to be to double-space the dialogue, as one would when starting a new paragraph. Of course, this is just my opinion, and I won't feel offended if you don't take my advice.

That's all :)

(Please note: I will still love your writing either way!)
