Hmm. I love this.

Beautifully worded which really enhances the elegant dance with the shadows and your inner demons.

The reference to the black hole is also very nice. Something that consumes all without any hesitation. Stealing your innocence, tearing away your heart. Nice element.

The ice as well. Contrasts hell and its fire but the fire from beneath the ice could be making it thinner by melting it? Not sure but also captures the idea of a heart void of feelings. Cold and lifeless. Nice.

I love rhyme. And you are really good at it. You use an abab pattern and at some points it doesn't follow that but it still flows very well. Nice :)

Adding nature adds a more real and natural sense to the poem so that works really well.

I love it.

Awesome
