United Federation of Planets, Constitution Class Heavy Cruiser and Klingon D-7 Class Battlecruiser.
These are drawn at 6 pixels per meter. The Constitution is drawn at a length of 288 meters and the D-7 at 228 meters to match their published lengths.
I changed to 6 pixels per meter from the original 3 pixels per meter, as I wanted more detail on the interior deck layouts and so I had to start over on the project. I considered going to 12 pixels per meter but the .PNG images are rather large at that scale.
