I'll start with this large design in the center.
This feels a bit big and out of proportion to me.
There is still a lot of space to fill.
This feels like a collection of uncoordinated items to me.
This fills the space nicely but still needs a little something.
I think this does the trick. And there is plenty of room for some interesting quilting.
