Makbar, the theme for Remnant is zerging, that is "throwing as many ships to the fray as possible".
You will lose a lot of them, but you can also replace them more quickly and easily than other factions. If you prefer a more defensive style of playing, then perhaps the Xin will be up your alley, since they have very tough, very powerful and quite expensive ships.
Remntant's fleet upkeep and max slots for both regular and capital ships will be increased to allow them to field roughly double the amount of ships regular factions have. I'm looking forward to the challenge of designing their ships, as they will have to look both good and be relatively low poly in order not to bog down the engine.
I'd post a video of me making a model, but since that process usually takes several days and involves a bit of backtracking and remodelling I doubt it would be very enlightening. And without audio commentary such videos tend to be on the cryptic side for new users. If you want to get into modelling, be prepared for the long haul. I can design ships like these only after several years invested in 3DMax and about 6 more months invested in learning how to use XSI efficiently. My next step is character modelling... well, it should be coming up real soon because I need to put a face to the alien menace.
Which brings me to the concept art Gamerking mentioned. I already have an idea of what the Xin should look like - completely alien. That rules out humanoid. I want them to be as strange and distant as possible, while still retaining the organic fleshiness (so that they do not appear transcendent or something). Their background must also be taken into account, that is, they evolved on an oceanic world, so they are aquatic by nature.
Actually, I thought of simply taking your common squid and mixing in some insect features and armored "clothing" and see how that will look like. But if you can make some interesting concepts, I'm open to new ideas and suggestions! If I like it, you'll get credited for design.
It doesn't have to be a squid-like creature, but it has to have the following features:
-non humanoid shape. That means no two legs, two arms, and a plastic alien head. 
-usable appendages. Fins are great, but you cant hold a hammer with them.
-menacing look. Teeth, spikes, bug eyes, or even just a general body shape, it has to convey a feeling of a born predator.
-aquatic race. It has to be recognized that these creatures swim and that their ships are full of water.
And that's pretty much it.
