Bought a house with xeriscape… any ideas?

Hey all!

Super excited because I just bought a house (my first one) with a decent size backyard. It is beautifully xeriscaped with native plants.

I have a dog who loves her some grass so I plan on making a small section at the top of yard by the cement to have a little lawn. I also really like the idea of putting a peach tree in there somewhere with a flower garden.

Anything you would do to make the yard look more professionally designed/intentional? Thanks in advance!
