this actually got more C&C than a lot of posts do.
They're all fairly well exposed, but they're just pictures. I don't mean that in a belittling way, but they don't really seem to have any clear thought of what it is you're trying to show the viewer. WHat you're trying to 'say' with it. First is a picture of a flower, it's pretty. 2nd is a picture of a falling tree. It's interesting if it's on my property, otherwise I just kinda think 'um, so?' 3rd has some potential, but it still just doesn't really say a whole lot to me. 4th and 6th are a kid. They're fine if it's your kid. Otherwise it's just another picture of a baby. 5th is a picture of a butterfly (or moth, not sure) on a hand. It's fine if that's your thing, but nothing stands out about it. 6th is a fine picture of cloud textures. I actually like this one, it's pleasant. But there's not much to it either. It doesn't have any point to it, other than just being a pleasant picture of some skies. Sure, that's fine, but such an image isn't going to generate much comment. It takes almost no work from teh photographer's creative element to get a photo like that. It just takes a nice sky and the right settings.
The last image has some potential to say something, but the random limb clutters it, and the strip of powerline in the upper right corner distracts. It's also framed like it's a person, without really having any reason for being as such.
Basically the common thread is thinking harder about what you want your photos to communicate. It doesn't always have to be a story, it can be a mood, or a feeling. But if you want them to impact people you need to give them something other than just being a pretty visual image to strike them.
