I don't understand this was a class project? Are these loops? What kind of class makes you make drum and bass? Awesome!
Any way. The drum roll before the 2nd drop is fun. And the song has a pretty sounds to it. If it was just loops you can do a lot with them in this world it is more than possible to take any loop and make it entirely your own. I think it is easier to use a synth, but a good sampler I hear does wonders.
