Okay, if you're going to film something like your backyard it's possible to make something interesting, you just need to think a little more creatively. Shooting with a wide angle on a glidecam (an unbalanced one at that) is probably the worst way to make things interesting. After five seconds we know exactly what your yard looks like and the rest of the video isn't interesting at all.
Focus on details, if I was told to shoot something in my backyard the first thing I would do is not shoot wider than 50mm on a crop sensor then try to find interesting details that people wouldn't ordinarily see. Waiting for good light is another thing that you should've done. The blown out, overcast sky made your subject matter even more boring. Finally the song you used was much too powerful for what you were shooting.
Honestly there's not much to critique there. If you want to make something that's "good" you're going to need to work for it. Go somewhere, think about each shot and how it should be composed/exposed before you press record, try to think about what you want your final video to look like and what you need to do to make that happen before you arrive on location.
