Extremely bright illumination often has a garish, theatrical look. Experiment with backlighting. Lighted trees in the background of a forested area creates silhouettes in the foreground. An uplighted hedge behind a shrub or tree will do the same. Don't illuminate every surface.
Shadows work to define lighted areas.
Create a different look for your property at night than it has during the day. The night view will often be more dramatic than the day view. Take advantage of the many lenses, diffusers, and mounts available so that your outdoor fixtures suit your situation.
