Try to think of all the possible ways landscapes can be useful: provide light or shade for various related purposes; provide spaces to entertain, lounge or for recreational activities; provide beautiful views; screen unattractive views; a place for pets; places for storage & utility; etc., etc. Do you need any of those things? Designing a landscape is assessing all the needs and finding (as much as possible) ways of fitting them in or accomplishing them.

You seem to already have a high ratio of impermeable to permeable surface, so I would do the edible planting in pots or boxes on the concrete, and clean up the rest for planting in the ground. These could include edibles too, of course. But don't put raised beds on top of the precious ground that is left. My two cents...

Looks like you have a large area for playing basketball in your yard. Is that something you do?
