You got a few real nice tones there with the samples you've created. I felt like the beginning was very slow, and if I were to make a full song out of this, I would probably start the beat from 1:02 and build on that each bar. My only other piece of criticism is that the volume is wayyy too low. I had to turn my speakers AND amp up all the way to hear it at all, which introduced a bunch of white noise. Other than that I think you got something you can definitely build and improve upon here :)
