The nice thing about Hunnicut is that he gives lengths with and without gun over hang. But, I agree completely with your icon creation steps. I box my dimensions, outline the hull, rough details, then add dimension ie, shading, shadows etc, then adjust as needed by eye.

I even thought of stretching the superstructure forward a pixel and not having such a large open area between the tracks. Heck if I would have done both those things i have thought we would only be 1 pixel difference. Lol
