Chiptune?

So, today I tried using a music tracker called FamiTracker. I watched a few tutorials and then I decided to try it myself. I came up with something without copying any tutorial... Here it is:

Now firstly, I'm not trying to promote my or any channel. I created a new channel specifically for this video, and I just wish to share it. Secondly, I don't know how to upload the file, so this will have to do. xD Plus, this way, none of you have to download anything, so that's good, right?

I'm open to any criticism, this is my first chiptune and I'd like a few pointers. Feel free to rate any number stars, I know the song is short but I started on it today and I could work on it some more. Thanks!
