Shot 1:
Not sure what I'm supposed to be looking at here. The girl? If she is the subject, then make her the subject. The pose is somewhat provocative w/ undone jeans, so I would much rather look at her than be distracted by some dude out of focus in the background. Is he a stalker?

Striped shirts are generally bad news for portraiture. As with the first photo, I'm not really sure what the subject is here. The guy? The beach? Did he lose his Wham album and he's looking in the sand for it?
Aside from the striped shirt (which is a big no-no) these are technically sound photos. You have good focus and exposure, though I think the lighting is a bit harsh, especially in the second image. What you need to work on is your composition:
- Ask yourself what message you are trying to convey. Is it clear?
- Watch for poles sticking out of people's heads.
- Consider time of day and lighting when shooting outdoors.
