First off, I think this has a really great rhythm. It is kind of unexpected and doesn't follow the regular 4/4 time most songs follow, if you know what I mean. I also like how you started to add a little line in between each of the hits. I think with some proper music making software you could be pretty awesome. If FL is to expensive for you then you should check out Cockos Reaper. It has a 30 day trial I think, and a non commercial license is really cheap, like 60 bucks or less, I can't remember.
