Modelling a Venator Hangar in Blender

For now this is a work in progress I am working on, I wanted to recreate this in order to learn new techniques. For now the result is not the expected but this is a start.

I struggle a bit with the lightings and contrast and I am having hard times to recreate the lighiting of the original image.

Also, Clones and LAAT (Vehicules) aren't made by me, the point here is to be able to recreate the ambiance
