The design above is called the Sub-Crawler. It is a gigantic excavation machine that is operated by two operators in Palestine 3000 A.D.. The approach of the design is very much the film method that is to apply details only to the part that is visible to the camera. The top sketch is the first iteration where there are more details on the body. While the bottom design is the final iteration where there is no detail on the body because of it is buried in the ground. In the actual scene of the graphic novel the focus is mainly on the head. Much of the detail is actually in the interior where the controller room is located.
The final 3D design of the head is not faithfully the same as the 2D sketch. The sketch came from pure imagination while the 3D design is technically accurate. The final design only has one head light and one level of pilot lights. It is not practical to have the second level like on the pencil sketch.
The reason for the second iteration is because I was trying to find a proper spot to place the entrance door. I finally found a good spot on the bottom right of the picture. The placement goes well according to the script. That also give an idea the size of human head to toe compared to the machine.
The visual treatment for the final print is not the same as the 3D rendered picture above. Though I was tempted to show it but let save it for the final.
