This style is meant to be more stylized than realistic (especially the water part). This style is more reliant on adding helper words to the prompt than most of mine. You still need to use a trigger (n0vuschr0ma style) for best results, but you might not get sand sculptures if you don't ask for them.

I usually prompted for a "sand sculpture with seashells" plus one of the following:

• viewed from overhead

• on a beach with a sunset sky background (or night, twilight, sunrise, cloudy, blue, etc)

• tiny island in the ocean

• with water

• with foaming blue water

• enclosed by ocean water

I included several examples of each in my model post.
