Really cool and bold adaptation, I love the sense of disorientation created by the harsh colour palette and editing style, extremely appropriate to the point in a Berserk story where the rules of the world break down to demons and madness. You've done an amazing job on the soundtrack especially, it calls to mind Hirasawa's soundtrack from the 90s anime but it's still definitely its own thing.
Berserk is not an easy work to adapt (many have tried!), *especially* as a solo animator, and while this is more of a rapidfire reel of the main emotional beats of the arc which would probably be a little hard to follow without the manga, the effort you've gone to is evident and it conjures a unique and powerful mood, which is the most important thing. You've made very effective use of limited resources. Can't wait to see what you direct next!
