Hi there and thanks for adding Space Academy to your list!
I had a quick read of the first chapters you have posted here. I think it's great that you decided to make it into your own story instead of keeping it as a fan fiction, because that will give you a much greater space for creativity in the storyline. That being said, it does of course show a rather strong Star Trek influence. How close you want to keep it, depends on you.
The action takes place in the very faraway future, which is interesting for me to read, even though my own story is in the rather near future. I will give you some more feedback once we meet the characters!
