This has all the elements of a classic seascape present in the frame.

The undulating tide leaving wet sand on the beach and creating a definitive line between the sea and the sand. The pier, which acts as both a point of interest and a diagonal line that leads the eye into the rest of the frame, and the moody sky above, catching the colours of dawn.

I like your understated editing, emphasising the mood of the morning, allowing those subtle purples and oranges to speak for themselves. The texture in the clouds really works too, with the shape and motion of the cloud mirroring the shape and texture of the water below.

A compelling seascape and demonstrates your ability to capture a dramatic scene and stamp your own style on it.
