Hi Andestine
This is my first try at uploading an image, hope it works.
Sorry for the rough crop, but I hope it will illustrate my point.
Ithink the combination of too much empty sea to the right of the picture + the pier end pointing to the left throws the perspective out of kilter and draws the eye away from the natural vanishing point.
Abit of carefull cropping and a little more sky may help. Experiment with the original by holding a couple of straight edges over the picture and adjust till you find something that works.
And yes it is a very good effort, just remember we are always our own worst critic.
