However, I suggest that next time you should use another program(3ds max, Metasequoia, etc). Milkshape is old, and you can see that in your model.
Also, you should use .dds files.
Edit: You seem to have a few stretched textures on it, a few of them are blurry because you stretched them too much. Try to keep them the same size.
Also, your texture files are bland. Freelancer ships make heavy use of tiled textures, especially for large, continuous areas, like the top and bottom of your ship.
I used only one 512x512 for economy, I ll try to remake it in Maya as soon as possible
