like this as its different as regards backlighting

Have you noticed that the horizon line dips to the right....and soon the ocean will be on my keyboard? If you are trying to highlight the shadows (as your title indicates) a closer down crop would have made for a stronger shot. I love the patterns cast by the shadows.

yes I no and thanks for advice

I wonder what aperture you used for this upload as you have significant blurring, perhaps that was your intention. I find this rather a romantic upload, it is poetic but could be sharper.

Frankly speaking, I don't remember the aperture, but the mood of the photo doesn't need to be sharp.
