Very cool stuff, I love the classic maiden vibe here from your music. I really dig "knights of the round" of all the tracks so far I think, although they all are quality. Your guitar playing is excellent across the board 🤘
As for the vst drums some suggestions for a bit more of a hard hitting sound you could look into MT power drumkit2: www.powerdrumkit.com which is a free program. I use this one personally and I think it sounds solid for a free program.
If you have the money, you'll get more out of toontrack ezdrummer2 which I've used in the past as a demo version. It has nice sound and has metal expansion packs you can get.
Keep em coming 👍
