You look like you live around me (Mountain Home area)
In my uneducated opinion. I like #3, cause it has a very interesting feeling to it. #13 has good color to it, and I like #15, cause, well, I just like bunny rabbits
You need to not be so hard on yourself, though. You have some good photos in here, and everyone starts needing to learn more. I am a beginner myself, but I will try and help you out a little. In some of your photos (#9 and #10), you have a little bit of the foreground included, but IMO not enough to make it seem like an intentional part of the photo. I would lower the camera down a bit more on things like this. Do you know about the "rule of thirds?" Perhaps when you're shooting a sky next time you can keep this in the back of your head. I think (though I could be wrong) you will be happier with your results. And if not, then forget me!

Remember its all about what YOU like, and to fooey with everyone else!
Whatever you do, keep shooting, and have fun!
