I really liked what you made! I'm probably gonna be singing that melody from 'Mutant' to myself for the rest of the day. I also really liked your lyrics and choice of harmony throughout the submission.
Some food for thought - I felt that the vocals were a little difficult to hear at times. The rest of the instruments were a little overbearing, especially the bass + lower frequencies. Maybe try readjusting the volume of the instruments so that the vocals are a little more in front, imo. Additionally, I found myself adjusting the volume when each track started to get a consistent volume.
Thanks for sharing your work :)
