Good!
I quite enjoyed it. I liked the way you varied a little in the melody, but still, it needs to be a bit more unpredictable. The rythm didn't change much, and you stuck with the same instruments. Also, a better drum beat would liven it up a little. Still, the melody's really catchy, so all in all, great job. Enough effort put into it, so I'll give it
9/10
