I took a look at your characters, and I really liked them!
One thing I definitely noticed is that they were kind of barren of detail? I couldn’t really learn anything about them from what I read except the bare minimum. There’s nothing stopping you from expanding on your characters!
What I saw I liked, though! They seem really good, and even if you can’t find a plot line to tie your story together, that’s fine. I can’t really either.
