Well, we can't help you if there's nothing to help you
with. We don't know what this ship is supposed to even look like, so how the hell can we tell you what to do to it?
I'm sorry if we're coming across as less than helpful (or friendly for that matter), but you have to produce something substantial for us to critique. Less than that is just a waste of both your and my time. I mean, compare your "ship" to something like this:

This god-awful sketch took me all of a minute to do, and it still has enough detail to get a basic mesh out of it very quickly. Do a quick drawing like this, and then make a model that has every single detail on it. Then post that, and you might get some constructive advice. OK?

EDIT: Christ, aldo did much better than me...

Well, he's a master modeller, and I'm ****, so I suppose that's to be expected.
