Wow, um, exposures are all off, backgrounds are brutal, post growing out of one guys head. It looks like you just pointed the camera at a subject without knowing anything about the camera, or any of the basics of photography. I'd go back to the starting point, buy a book, and really look at what you are shooting. If there is no light on the subjects face when they are back to the sun, there won't be any light on the subjects face when you take the picture. Look at the background, it as important as the subject you are shooting, keep them clean, no wires, no posts, no trees.
