Tracie, thats a lovely garden and a great size.
Rather than straight narrow boarders I would add some curved sweeping borders that include the tree, possibly replacing the dead one, and perhaps with the lawn going in-between them as a path. A border on the left up against the hedge would be nice, but with a paved path in-between running along the hedge for cutting it and sweeping up the cuttings. Narrow borders around the perimeter of a lawn can look like the planting was an after thought, but obviously its your choice.
I could happily spend days and days doodling with pen & paper drawing designs for a garden like yours, there is so much potential. Id definitely keep a good size lawn, but also increase the borders to get more plants in.
