Since you played primarily to the downbeat, it sounds like a Military March (not saying that's a bad thing). To be honest, it's a little dull to be listening to constantly. A few more 1/8 notes for the bass part could help to add a little more energy to the song. The song can also loop better because it cuts into the middle of the count before the measure finishes. Not a bad attempt. Keep it up.
Thank you for a friendly review and the nice tips. I'm sure I'll learn better over time, obviously since this is my first. My next song won't be a loop so I'll learn a bit there since it won't be so short.
