The classic era ships don't look bad at these sizes next to the Galaxy to me, while maintaining internal relative scaling fairly well and also making Galaxy to Excelsior and Galaxy to Oberth seem more like what we saw on TNG. It flies in the face of official convention, but that in and of itself doesn't bother me. What I wonder is, does the preponderance of evidence agree more with the above, or more with the official scaling?
Thoughts and opinions?
Actually, this scale ends up working both for the side views of the Tsiolkovsky and the Stargazer when shown flying next to the Enterprise-D.
I also have felt that the Connie was much larger than "officially" stated, and likewise the Oberth too. I'm totally fine with your interpretations here.
