a 40 feet container

First I'm making a 40 feet container. The containers will be the most seen object in the movie. It looks like just a box. Do you think it would be slightly boring to make this? I thought so, but references showed me some interesting features on it. It was fun to make them even they almost cannot be recognized from a distance. (Actually I'll bake the detailed model to a simple box model to make distant objects.)
This model was made and rendered by modo 301.


I'll make variety of textures to make variations.
