I agree with the previous poster. I'd center the larger platter on the top shelf and use a set of three succulents in identical white containers on the middle shelf.

I would leave the top shelf as is (move the jar to the right a tad). On the bottom shelf, I would remove what you have and add a few cookbooks with some white or blue bookends and that little white ball you have on the platter down there.

The scale adds to clutter. I agree with the others.

You could leave the scale up there with the books instead of the little white ball. Is there a wreath behind it? Remove that.
