You have a very good way with decriptive writing. I like the premise and I like the threat of what could be.
The dialogue needs work and that said, don't misunderstand: It is good. It just seems sometimes that everyone is speaking with the same tone except the bully boss guy in the beginning. He's blustery and you got that point across very well.
Alexi seems a little unsure of himself, which I found disconcerting in a warship commander. Perhaps more dialogue between his crew and him would help me understand his position better.
I however, am a dialogue whore most of the time so take this with a grain of salt because you kick ass in description and again, I like the premise.
