I don't think it's your basic settings or processing. Most of these seem to have fine exposure. (The exception is #2, but hard sunlight at the beach is difficult to get right.) The color is decent — if anything, a little too 'real'; maybe try to move a little out of your comfort zone in terms of color, saturation, etc. Play with some of the filters/presets in your editing app, not as a crutch but just a way to stretch your creative mind to ideas you're not considering.
Rather, I think it's your composition. Most of the images could be a little closer in, or a little farther out. Start looking at the edges of your frames, not the middle. For example, #4 (the motorcycle) chops off part of the Harley logo. It feels to me that either you want that in there, maybe as a more graphic element, or you don't — right now, it's kind of half-in, half-out. Similarly, the kid's arms on #6 are oddly cut off. Closer might be good, farther might be good — but now it's uncomfortable middle.
As an experiment, try shooting the same scene from different distances (I mean you literally moving yourself, not just zooming), and from different angles. Walk around the scene and take a dozen pictures of the same thing, not just one. Also, shoot from a relatively far distance, then judiciously crop in editing. How far can you go? What does one crop 'feel' like vs. another?
Finally, I have a little mantra I say to myself: 'Don't take a picture of what it is — take a picture of what it is about.' That is, how does this photo tell the story of the person?
Hope this helps!
