It's coming along well. I just need to develop my characters more. I really want to get a good sense of them and tell enough about them that you remember them in future stories. Some scenes need to be fleshed out a lot and I have ideas for additional scenes.
For this, remember the mundane. Have characters talk amongst themselves and banter, not everything has to be a life-or-death situation. I always look at my characters as normal people who happen to work in space, so be sure to focus on their relationships and have easy flowing dialogue.
Then throw in little details here and there, and not just about the main cast but extras and recurring characters as well, flesh out the ship and make it feel "lived in".
