I agree about getting the jewelry off the tables in the center and the tall pieces off the shelf. I would also suggest moving the tables to the rear of the rented space to close off the back of your selling space. While closing off the end of the selling space is sometimes frowned upon, it will give folks the room to step back and see what is hard to see down low on shelves. Most folks and especially the elderly shoppers will not want to bend way down or kneel to get a look at hard to see items because they have a hard time getting back up or are afraid of knocking items off when the displays are so close or both. If you don't want to close off the rear of the selling space, maybe you can incorporate the tables to elevate some of the smaller shelf pieces and still keep a few items on the tables as well.
