Hmm.
It sounded very desertish that is for sure... but you selected the wrong loops to plug in here and there. They didn't sound good when put together. It sounded OK, but this song doesn't deserve any more than a solid 3. It is good at some points, but you simply didn't create the song very well.
You need to go back to the drawing board for this one. When making your songs, make sure it sounds good instead of OK. It needs to sound good to other people as well.
The main reason it didn't sound so good was because of the drums you choose and loops. Just experiment some more and I am sure you will do just fine.
Remember, the best example I can give you of Garageband loops is my song
(::Creation And Its Purpose::)
You can find it easily because it is one of the first songs i ever made.
I hope that helps you. You are just starting out, and could very well be a cool artist.
Cheers!
