First submission? First review. :)
Hah. Either someone's going to beat me to it while I'm typing, or I'm going to end up giving you your first review. :) Let's look at your song.
Your song's a bit bland, boring, etc. Your melody's a big part in that - if you want to fix it, either make it longer or change the entire style of the song. I'd suggest the former.
You try to keep the drum patterns new throughout the song, and it works - the problem is that you didn't put very much time into them, so fresh as they are, they're still boring.
Then there's that it doesn't have an ending. Personally, songs that don't have an ending don't cut it for me - work on that, too.
Still, given that this is the first thing you've made, it's pretty good, so keep practicing. :)
Ah, while I'm at it - why don't I suggest you review my songs if you have the time? I'd appreciate it. :)
