For the comm badges, I was thinking that they would look perfect if you made them the same size as these ones,
but obviously they would be the Voyager color scheme, which is different to the First Contact/Nemesis badges but only slightly.
It may sort out the blurryness aswell if/when you make the badges smaller. But then again, it may not. Again, Ill let you decide.
