My only comment is I didn't know this was a short story before reading it. This could easily be expanded into a full length novel. There were lots of places where I wanted more background, more character building, world building, etc.
I liked the space twist on the Romeo and Juliette theme, but I had so many unanswered questions at the end that I was left with a "What?" kind of feeling.
Give me more, I know it's in you! ;)
