Thirty inches is an extremely common lamp height these days. How you use a lamp, where you use it, shade proportion to base, the harp, the finial, all matter, for a good look. All said, you're probably not a lighting designer and a lamp either looks right, or it doesn't. I'm not a lamp creator, either, I DO know what looks good where and on what. The price of lampshades, unless you head to Target or the discount stores has soared..... and all considered? Maybe not everything needs a rescue: ) because you might have a hundred bucks into a rescue even with no guesswork. https://www.lumens.com/pinn-table-lamp-by-adesso-ADS2392549.html?utm_source=google&utm_medium=PLA&utm_brand=Adesso&utm_id=ADS2392549&utm_campaign=1440416580&gad_source=1&gclid=CjwKCAjw88yxBhBWEiwA7cm6pSIWUETxgN8zfZpAdr-pQJcOAP3SGhb0cYp8YgvFnMr-sEjwql9dVBoCkuIQAvD_BwE

The thing I immediately notice about the back vs the front— the back has more substantive landscaping and trees. I think a new landscaping/ hardscaping plan — think deeper/ wider beds, larger shrubs, maybe a patio area, some strategically-placed trees—would make a huge difference in your front yard.

I have three window seats in my house as well, and imagined my children curling up in the spot to read a book. One pair, flanking cabinetry in my family room is 22” deep, which is too narrow to comfortably spread out and read on, and the other is 25” deep. They have custom made, great quality cushions which I felt were important for comfort as well as appearances. Despite this and beautiful views, the only users in the past twenty years have been my cats! I’m sure your room will be beautiful, and the seats will add a nice architectural feature, but I found that they just can’t compete in comfort with a great club chair or even the sofa.

I wouldn't add anything until you get what is already there in better shape. All the bushes cut into ball shape need to be let grow naturally. Some of them may need to be removed. Use annuals until the bushes are grown out. I would also paint the door to match the railings and window trim I don't find that the red is complementing the brick. Hostas, Ferns & Hydrangeas are good in north facing gardens.
