I wrote the following:
Having finished her breakfast, Tsuki went to take a walk at the beach. She made her way through the sand barefoot, feeling the cold water and foam run between her toes. This was one of her favorite sensations in the world. It reminded her of a distant childhood. Afternoons at the beach building sand castles and swimming under the sunset. Those days were only memories now. Did she still own them? She sat on the sand and gazed at the sea. There were still enormous waves, so high that they looked like skyscrapers. A big tree trunk was being tossed up and down among them.
I was wondering whether the rhythm/flow in the passage above (the bold section) is OK. Should I add a third item in the second sentence to make it more complete? Is the last one sentence too abrupt?
(The "did she own them," part has to do with the theme of the story. The story is about ownership and belonging.)
