PSPUG Photo Workshop.

I worked on this one about an hour.
First I removed the objects from the background and pasted into a new image, rotated it, drew a vase with the shapes tool and colored it.
I used pebbles texture to set the vase in and also to fill its mouth.
I used a blue mask to fog and haze the image, then sharpened that twice. I used the clone tool to spike the top just a little, then exported as jpeg.

These next two tell a story. I used a lot of copy and paste, some tubes, and screenshots, and the clone tool to blend the sand. Each took about 45 minutes.

The clock took about an hour. I used cut and paste to put a face on, tubes to add angels and wings, and some sparkles. I drew a shark outline in the water with the pencil tool. Finally, I softened with a mask to give it a dreamlike quality.
