I'm sorry but I have to respectfully disagree with Drisley, although the last image has some merit, there are fundamental flaws in the first three.
The sun dominates and should be secondary to the composition, there is some awful halos around objects, flare is distracting and central major elements don't help.
I can see where you are going, and how you have tried to retrieve the exposure, but in this instance it doesn't work.
You have some fabulously creative work in your gallery, these don't come anywhere near it.

Concentrate on equipment and you'll take technically good photographs. Concentrate on seeing the light's magic colours and your images will stir the soul. - Jack Dykinga
