Personally, I think that some of those textures may still be too bright, while others are looking good. The "seats" looks like a nice subtle effect from the screenshot; the ship exteriors are probably still a bit too bright (the fighter in particular). The issue is not so much what the maximum intensity is, but that the intensity is so uniform across the ship. I think it would be more interesting to have, for example, the engines be fairly bright, with the rest of the green parts having a more subtle, dull glow; maybe weapons could be intermediate, or something. But this is all really just a matter of aesthetics and personal opinion. As you said, anyone can edit the textures to change brightness, distribution, etc. In fact, I may poke at some of the textures myself at some point; just not tonight.
