I would build a rock wall and path with stepping stones off the patio, starting where the dark chair is on the edge. Make the path obvious, and interesting. I would make the path curvy, with larger rocks along the way for interest, then have it lead to a little sitting area to the right where it's sunny- but you could put an arbor over it for a little shade.
I would decorate with pretty copper things, like butterflies or dragonflies. And then for color, I would have big pots with annuals, both on the patio and off! Shepards hooks are pretty to hold hanging baskets too.
If you didn't have access to rocks, use shrubs that you can shape along the way so that it looks serene. Sounds easy? Lol
