I see where you are coming from. But it seems that in the 150m version, the average person wouldn't be the same height as the cockpit window. The models and the interior seem to have a window of maybe 1 meter. The line drawing looks like the window is closer to 2 meters.

…

To me, it just feels like it should be closer to 120.

I think I know why you feel that, the side view of the cockpit is deceptive. The shape you see in there is not the window but the red "missing" part surrounding the window. I made a little front view of the head section to show you better the proportion between the surrounding shape I mentionned, the window and a human, and I compared the different approaches:

As you can see the 75m and the 300 m scales just don't feel right, the 150 m version is pretty much ok with the 1 m window, don't you think?
