very nice photos! Greeeaat colours!
The first one looks almost like an oil painting work to me.
Pity the sun in no 2 and 3 is right in the centre of the photo and the sea level divides the photos in two equal portion--may be you could position the sun a bit to the left or right and try leaving more room either for the sky or the sea--depending on what you prefer: the reflection or the clouds^^.
