First of all, on the screenshot above the zoom is way out.

Comparasion of any photo and screenshot proves nothing. I think you are well aware of the camera lens an MSFS general distortion and of course MSFS ZOOM distortion that change any model appearance dramatically.

Ideal model? No problem, does anyone have the 757 engineering drawing with cross sections? If so, please send then we'll re-check our model geometry.
Otherwise, all talks about the model geometry are really about nothing.

And please do not forget, the game modeling is always an ART.
