Loving the whistles throughout main melody. It gives it an epic feeling. However, I thought the proceeding elements were dry and unwelcoming. I could easily see you placing automations throughout the song to bring in the beginning sounds and give it more variety to give it a serious oceanic deliverance of sheer chaos. I seriously love that part. It's post-apocalyptic; and that is one of my most favorite genres -- ever. Even in my music, I always combine life and monster in nearly everything I compose. However, in your music, I only experience anger, lost, contemptment, blindness, pain and sadness.
Perhaps you would enjoy a discussion? You seem to have a very dark mind, which leads to only creativity.
Cheers, mate.
