I really like the second one from the three shown above, lovely pastel colours, great composition and well worth getting up at 'stupid o'clock' for in my opinion. I also like how the dawn coloured cloud to the left, along with the rock in the sea, gives the image a counterbalancing weight for the castle.
So all in all, a really lovely image and if you have any space left on your walls, then might I suggest that this would be a good shot to fill it with
