Proper Display

I've been playing around with my Star Wars Dioramas and found the best way to display them in my current setup is to have a couple elevated in the back of a shelf and a couple actually on the shelf in front of them. This setup has some of the Dioramas just sitting ontop a cardboard box. Problem is the boxes are kind of smaller than the sets and each set has about a third of it just floating. Will this cause the sets to be damaged in the long run or is this perfectly fine. submitted by ...
