Beautiful house! I see ornamental grasses. (Are some deer proof?)

Cannot see how it is in the photo, but if this were my house I would have a "plaza-like" termination of the walk where it meets the entrance steps. It's a nice set of steps and entrance and in order to keep with the same niceness, one needs to be able to step off that bottom step at any point onto the walk ... not just at a 4' wide section of it. Maybe that's how it already is. Cannot see.

As far as planting, you might include a couple more shots from the exact same vantage point, but that are angled (pivot) so as to show 20' or 30' to the right and left side of the house. (The planting for the house front does not just "quit" in line with the house corners. It's in a setting that extends to some degree beyond those corners.)

If deer are a severe problem in your area, and you won't be fencing to keep them out, you really need to consult with local nurseries or landscape professionals that know what holds up in your town. Standard deer resistant lists of plants have become nearly worthless in some areas due to extreme deer overpopulation. Noting what plants you admire and resist deer predation in your neighborhood, consulting with neighbors who garden or also maintenance gardeners in your town will help expand the list.

Design issues are another issue altogether, but the house is nice looking and shouldn't be difficult to landscape. Perennial grasses in general do work well in deer country, you can add grassy foliaged plants such as Acorus, Carex, Juncus species to that mix, along with most all Iris species. Your local county agriculture extension office, master gardener association or local university or Botanic gardens, along with good retail nurseries would all be good sources for deer resistant plants.
