About this 3D model

Here is The Stratoship H-22, from Hergé's famous albums "Mr. Pump’s Legacy" and "Destination New York". In the albums, the proportions of the plane change regularly, I tried to get a harmonious model of it. If the modeling in Tinkercad was relatively fast, transforming it into pieces that fit together pretty well took much longer, and can still be greatly improved (windows and windshield, in particular).
