It's impossible to get a sharp photo with a long exposure in wind. Seeing as it's always windy in your area, you need to shield your camera from the wind somehow.

The Crockwell picture is heavily edited. It looks pleasing, but that lighting would never occur naturally.

Also note how minimal his composition is. It's clear that the subject is the iceberg and it shows a lot of depth because the foreground is open and the clouds vanish into the horizon. In yours, the rock in the foreground looks like it's blocking the view, and the icebergs are small and distant.

There isn't enough contrast in your photo, it just looks dark because you're shooting into the sun. Unless the sun and sky are your subject, it's best to keep the sun out of the frame.
