Yay, I love the instruments and melodies. The bass at :40 is also quite catchy. It somehow combos well with that quirky, bright piano. Nice use of synths. Structurally, there isn't much variety, but it is very short. I also liked the instrument you used for the snare. Anyway, I think you could do more with this. It has a lot of potential, even though you wrote it above the ocean. ;) As for the chord changes, I think the bass indicates those more than any other instrument. Especially pay attention to the notes the bass plays at the beginning of every measure, and you could use those to make some pads or something in order to expand upon the ideas you have in this piece. Still, you did a nice job with this one! :D Keep it up. ;) Also, have you been getting my PMs?
