A starfish on the flats at low tide, with the light going purple.

The sand is ribbed in every direction here and every ridge is holding a highlight, so the bottom half of the frame is nothing but texture. Running up through it from the right is a tidal channel that stayed dead flat, and it is carrying the orange out of the horizon back down toward the camera. The starfish sits low and to the left on the ribbed sand. Out on the bar, a small bare tree stands against the light.

Purple and orange, texture below and space above. Vertical, and a good one for a narrow wall.
