Oh Rio It has a nice feel to it and the bass is cool bouncing around, but there is a scratchy bit of percussion just before the 4th beat of most bars which I found a little distracting. It's not terrible it just kinda took me away from the melody.
at 0:45 the frequencies/ harmonies/ levels clash a little, I think there might be too much going on there
at 1:14 there is a strange bass rhythm just before the build up. The build up was awesome though, it works well.
Some of the longer held melody notes perhaps could have used some variation... maybe some vibrato here and there just to sound less sterile. (eg 0:25)
Overall I liked it, and it sounded pleasant but I think the melody could have been a little more catchy to make it a bit more memorable.
