The first one is pretty good. It reminds me of a low qual advertisement for a movie you see on myspace or something. As for the rest they're very generic and simple. The "A beautiful girl" image reminds me of the new "Step Up 2" movie poster for some reason but that's not a bad thing at all.
In my opinion you should expand your horizon and think about bigger, better things. Adapt your own style and wow us with what YOU can create, not 4billion other web users.
Sorry to be harsh but they're the best words when you need to adopt a personal style.
