I really like these kind of photos, because in a single click there are several messages transmitted by the contrasts that everyone can get its own interpretation out of it.
The beauty and the calm of the sun and the sea, and I would say the sea gulls as well, they are the exact opposite of the clouds, the waves that give you movement and agitation.
Even the colors behave the same, the cold blue and the warm yellow are there "fighting" for the supremacy in this image.
