The airship is a relatively important character for this production, as it is the main element that connects the whole story, so I wanted the plane to have a lot of details and features, and to satisfy these I found some references on the internet as shown in the picture below.

Because of the setting of the story, I wanted the ship to have some technical elements but not be particularly edgy and advanced. So I found these reference images

After searching for a reference image, I made some combinations and modifications to some elements on each image. I drew 20 silhouettes of the spaceship in Photoshop first, and then selected a few that I was happy with for sketching and modifying the details.

After finishing the detail sketches, I will base my 3D modelling on these sketches.
