About the greebles, I'm not actually sure if I'm going to texture it to look like greeble or to model it. I'm modeling it, but I don't think it looks too great... I'll have to texture it to see if it fits.
And there is a little noise and smudge thing going on in the texture, but maybe the image is to low-res to show it clearly. I won't do much more scorches and dirt because I think it doesn't fit the general MediaVPS style, most ships are not that damaged and teared down.
