It looks like a pleasant porch. To me, the point of a porch is to sit and view the garden. You have a palm facing the sofa. Can you put a few more items in that garden? If it's really dry, perhaps an arrangement of rocks, but there are plenty of pretty native plants that do well with low water. What's on the trellis facing the chairs? Is it fake greenery used as a screen (why?) or a lovely, flowering vine?

Fake greenery on trellis to hide view of neighbor. This is in az so plants are hard to grow

Something natural like woven wood or bamboo would look a lot nicer than fake greenery. It looks tacky and fades.

I agree with planting a garden. Here are two links at a website I found for Arizona plants:

perennials

Vines

If you click on the words 'perennials' and 'vines', scroll to the top for more choices. They even a page for plant combinations. Since we don't know in what part of Arizona you are located (Tucson area, Flagstaff, etc. which can have different climates), you would need to check for plants that are adapted to your specific region. Check with a local nursery if you can. I would also suggest going with native plants as they will probably do best. And add more (in number) colorful pots might help, too. It looks like a relaxing spot!

Replace the astroturf with a colorful outdoor carpet in blue and coral to match the pillows. The dotted pillow is a dud sorry.

Move the awkward table somewhere out into the yard as a plant stand or with two little cafe chairs.

Angle the loveseat in the corner under the windchimes.

Get ottomans for the feet and side tables for drinks.

Hang string lights. We had no outlet so got a socket converter for the porch light...now the string lights go on when we flip the indoor switch...fun.

Wood slats as a screen instead of the trellis, and place the trellis behind the loveseat in the corner as cute decor and soften the corner.
