This is nicely styled.
As Superman was to some extent based on Nietzsche's Idea of an Übermensch, I actually think in this dark rendition his symbol could be related to "Alpha", to nice complement the "Omega" on Darkseid.
In any case, I don't find a dark take on Kal-El to be super compelling outside of Elsweworld stories, but you really caught an supremely imposing tone here.
Thank you for making this.
