First of all, change the music, that song is way over used on YouTube and is quite annoying. Add some effects instead of fade out and fade in, that's an easy effect and is also overused. Get a video editing program that's better than Windows Movie Maker, that's not a very professional program, it's just basic, you can't do much with it. Make your music go with your video, for example look at this video. See how the song goes along with the video, in sync and all that.
