They're all kind of Okay for a beginner. Seems like you're at the point where you've learned most of the tools in photoshop, now you just have to learn how to use them effectively. I would suggest maybe looking at some PSD packs in the resources section or google. Also look at some tutorials. Anyways keep working and I'm sure you'll get better.
I think the first is the best
I'm digging the last one.
