Consider small stepping stones
We don't always need a solid walkway, sometimes stepping stones to get you across a planting bed is all you need. Rules only exist if you want them to; stepping stones don't have to follow the entire path. Maybe it would be best for your yard to have stepping stones that break up into the lawn just to give you an entrance. They also don't have to go from one location to another. There is no reason why stepping stones can't give you a path in a landscaped bed that leads just to a shady spot or a favorite plant.
Loose boulders add interest
Loose rock formations within your landscape can add focal points and break up the expanse of plants, mulch, and flowers. Rocks can be placed in the garden in a multitude of ways. Usually people find odd numbers more attractive and like to have a taller or focal stone often set to one side of center. There is a type of Japanese rock formation with one taller stone surrounded by smaller stones on one side that is supposed to represent a teacher and students. It would look lovely with Esperanza behind it and muhly grass on the side in a very Galveston interpretation of a classic formation.
Cairns or stacked formations
The cairn is a traditional formation for rocks where they are stacked against and on top of each other. They were often used on trails for markers and also for remembrance. Galveston winds make cairns more difficult, but you can still have clusters of rocks stacked against each other. Size and location are what matter in Galveston, you want your rock cluster to be sheltered from heavy wind if you are placing rocks on top of each other. And maybe consider a smaller cairn made of larger rocks that are not smooth to roll away.
