Here is a picture of the full scene thus far, showing the work on the boxes and the shelves at various angles. Note: only 3 shelves were manually cut out and duplicated for length. Since there are a total of six shelves and the perspective points to the middle, the three I made could be duplicated, mirrored horizontally and positioned opposite the others. I set up a horizontal guide to work as a horizon line for the perspective in the scene.
