Here I'm showing how I make an aircraft technical image.
First, I draw in canvas the flat image, no shadows, no light, no details, only the limits of the image and the words and drawings of the model.
Second, I add shadows and lights. The lisht are low here because the white color of the model has a lot of light. Add more is make an error.
Third, add details. Line of panels, some details, etc.
Then I usually make the final details and the volume of the windows. The dirt is added too for make a sensation of reality.
In some cases we must tweak the model because there are not many photos as we do not know their real forms, and experts warn then crash and possible differences with the flat of the model.
