To gather and think, another houzz article -- art deco: [https://www.houzz.com/magazine/so-your-style-is-art-deco-stsetivw-vs~2131564[(https://www.houzz.com/magazine/so-your-style-is-art-deco-stsetivw-vs~2131564) "Not natural weaves and plain fabrics, but graphic patterns and sleek textures. Mix vinyl, silk and satin for layers of tactile interest; choose rugs, carpets and upholstery with geometric, rhythmic motifs. Animal prints are showy... Lacquer, polished wood and metal, and glossy paint combine for a slick and gleaming effect. Sprinkle glass and mirrored pieces...."

I would move the wing chairs facing each other directly, so that they make a U shape with the sofa. Cushions. Put the yellow cushion on one of the wing chairs. For the other wing chair, choose another bright color from the painting and buy a cover for the black cushion. To test this look, find a scarf/tee shirt/anything to wrap the black cushion in. Leave only the matching cushions on the love seat. Bring back the plant and put it near the window, raising it slightly and centering it in the space so that it fills the corner better. Center the tripod light in its space too. I don't see a good place for your end tables. Definitely not blocking the traffic path. Take all your family photos (from the end tables and from the top of the secretary desk), and make a gallery wall where a person can walk right up to them and see them easily. Hallways are great for this. If you prefer them in this room, put them on the short wall to the left of the kitchen where you now have one small piece of art.

Beautiful. You might consider an awning over your patio door. https://www.ebay.com/itm/40-x-80-Door-Window-Canopy-Patio-Awning-DIY-Overhead-Door-Clear-Decorator-/192387040987 Especially like the materials you used for the steps and landing/patio as well as including the fountain/bird bath but do take care not to decorate to the point of adding clutter your space. Potted plants flanking your door could add a welcome vibe. You might add other plants and/or wind chimes with posts that can be mobile: a wide holiday tree stand can also hold a4"x4"x6' post for hanging brackets and solar lights to be put where you want them when you want them. Since you have multiple sections in the southern sun, you might consider which one you could add the shade of a pergola over it (or gazebo by it) without blocking the sunlight to the other sections (likely the western most area) and decide if a small pergola or gazebo would suit your plans for the use of the patio. While cushions could be stored out of the sun when not in use, as you choose your furnishings, so please remember that the southern sun will bleach/fade the color fabrics and even furnishings such as wicker whereas your black metal furnishings could easily be repainted as needed so you can avoid making decisions you might well regret. Even if you prefer new furnishings for your summer use of your patio, your metal furnishings could be repainted and set in another, perhaps shady, area of your yard with their legs on individual pavers with their tops at ground level. Your view from your patio will matter so consider what you can do to improve any areas you might prefer looked better even if it is only adding a green hedge visual around the edges of your yard. Pick shrubs that will look good year round. If you are in Zone 7, consider Aucuba or Camellia or the type of Abelia bushes that keep their leaves year round and provide color and/or blooms. Looking forward to your after pics.

How about a pattern you like with colors that match your existing solids. Then you can mix and match. Looks like you've pretty much got beige and brown there now. Do you want something subtle or bold? Dark red or blue would be an option. A bolder accent color would draw the eyes to the space and make it look more inviting. As would maybe some bolder accents on the tables or walls. Like a big metal candle lantern or flower pot or metal sculpture on the wall. We got some garage sale nautical art to hand on our porch wall, under the roof of course but not fine art that will get ruined by a little weather. We even have a sign that says, "Welcome to the porch" and then lists all the fun things you can do there. Kitschy but makes the space look inviting.
