Please Crit This Metal Version of Led Zep's "No Quarter"

[Crazy Luke]

Here is my first cover song in this forum where I took a led zeppelin song, "No Quarter" and made an upbeat metal version of it. Let me know what I need to improve here.
I have two versions: Mix 2 is the full length track with a 2:30 minute intro, and Mix 2 (Sample) which starts up with verse 1 on.
- Thanks

Here is, IMO, a better mix of my Heavy Metal version of "No Quarter" by Led Zeppelin. It's a long (but interesting, imo) intro, so if you want to skip to the 1st verse, it starts around 2:20
