This is the way I want sunset/sky pictures look like! You can still see the sun behind those massive clouds and the sky is coloured in different tones of red and orange to yellow AND blue.
There is no such reflection in the sea as it would be if there was a lake, but you can see little waves, which brings some movement into the photograph. I also like the details which are everywhere, there's nothing out of focus.
It might be better if you could see a bit of beach or any land so that the viewer can see (in some way) from where the picture was made.
