Good job. Excellent transitions, even if the voice wasn't telling you there was one, it was still very smoothly done. I liked the whole song, you never got bored, which is incredibly crucial in a song without lyrics. Also, my biggest problem with it is the gunshot addition in the very beginning. It was WAY too loud and even offbeat most of the time. It sounded awful. I apologize, but I almost gave you a 2/5 and quit just because of that before I heard the rest of the song. but 8/10 because of the gunshot and 5/5 because that was the only qualm I had with it.
Please contact me if you would like to use this in a project. We can discuss the details.
