This is a pretty decent fanfic. Bah! More than pretty decent. There are a few grammar mistakes, but since English isn't my native language, I might be wrong about that. Anyway, you are off to a good start with your fanfiction, Thlayli.

Holly and Broom didn't get much of a screentime in tv-series (nor in fanfics as far as I can tell), so it's nice that you decided to write about them. Futhermore, it's great that that Captain Broom was finally able to tell his stories about Redstone to somebody without any interruption.

"Redstone sounds like an amazing place. I am sorry that I was never able to visit it. I would of liked to of watched the sunset with you and to of seen those stones."
Aww... That part was very sweet and the last scene with Bigwig was both cute and funny. It surely made me chuckle.
I think you should write more WSD fanfics.
