I like how the bushes and trees cover the fence. Don't like statues Good example of privacy planting, with trio of evergreens at the corner flanked by two faster growing crepe myrtles that frame the ornamental pots.
Keep the garden vertical. That's why it's good to look for shrubs and trees that max out interest as they grow up, not out. Try dwarf varieties for a small backyard, as well as more columnar evergreens (bonus—they boost wintertime interest, too).
