Where to begin...
1. The photo of the Lifeguard stand is the only one you posted that has any photographic merit what-so-ever.
2. All of the other photos have serious subject issues. And when I say serious subject subject issues I mean they either don't have a subject, the subject isn't clear, or the subject is completely uninteresting.
3. Take a look in some book, magazines, or online at really good photographs. Try googling beach photos. Now find some you really like and ask yourself what the differences between yours and theirs are.
4. You clearly didn't read the rules of this forum before you posted here. I'd suggest you do so before you post here again. And take a few moments to read the other stickies as well. There is some great info there.
Welcome to ST P
I'm not saying that stupidity should be punishable by death. But I do think we should remove all the warning labels and let the problem take care of itself.
