It's cool to see you learned a lot from this exercise, you did really well from someone new to this style! What's immediately distracting me for however is the popping sound that occurs sometimes after a note ends, that's a common occurrence with certain synthesizers, if you give the notes a microscopic amount of release in the vst's envelope it should fix that issue. The rhythm and phrygian sound of battle themes were both well adapted. I especially liked when the bass rose by a semitone over the course of the main melody, it added a lot of intensity! For the section at 1:33, the line by itself is good in creating variety in the sound so it's not all fast-paced, but maybe one extra voice there sustaining a note would help it sound not as completely empty. But overall this is great!
