Thank you so much for the extremely detailed feedback, I really appreciate it! I totally agree with some spots feeling empty and/or patchy, but I don't know how to address them yet. I'd appreciate any further advice there.
I understand your concern that it's easy to skim over the foreshadowed bits of the melody. Maybe a harmonized part could've drawn more attention to it.
You're right about the mysticism being a big part of it, I really wanted to invoke that fantasy vibe and kind of lost focus on making it sound like actually creating the weapon. I'd appreciate your clarification on what missing elements you think should be present :)
