Pretty cool. Did you create the melodies yourself? I thoroughly enjoyed them. I guess my only complaint is about the volume levels of your instruments. They just kind of blend together and make everything sound muffled. Just be careful next time to create space between each instrument. The drums and the bass is also very important. Overall, you did a really good job on melody variation as well as chord progressions and such. It kept me interested throughout the full 4 minutes of the entire track.
Keep up the awesome work. :) Have a listen to my new drum & bass song and let me know what you think.
