well
it sounds pretty much like the typical samples from the fl studio soundbank, that's the only thing I saw that wasn't good here. I liked the other things here though. The bass sounds pretty nice, and it has a nice little melody. Not so sure about the square, it's a little bit too digital for the track and had quite a lame melody.
I'll suggest you to fill your tracks a little more. This sounds more like the base of a song.
Pretty good stuff!
