I know someone here is going to interpret this as me being insulting, but now that you are more or less mastering creating these kinds of meshes, and UV mapping and texturing them, I'd like to suggest that you start to go back over them, add little bits of detail here or there. Add subtle curves to the large, flat blocky areas, add little greebles, recessed panels, slightly chamferred edges to the pointy abrupt ends.
More and more it'll make the meshes look more realistic. You've got the low poly technique down, but why limit yourself to that? You look to have the potential to create very detailed, possibly ornate meshes, but you keep them rather primitive (in regards to angles, detail, etc.)
Now, I may be grossly mistaking what the WC universe is supposed to look like, but I do think that there's room for a lot more detailing, and subtle model changes without detracting from a blocky, utilitarian look to the ships.
In any case, keep modelling, wether you consider what I said or not, you are doing quality work and in short time.
