My arrangement can be heard here And here's the original for comparison. I know the drums are a big area which need improving, but I'm terrible at writing percussion. so some advice would be much appreciated. Other than that, I think it's mostly mastering I need to take care of, but that's also a field I'm pretty new to. I did my best, but I'm sure it needs more still, as well as any fine-tuning to the arrangement that I might not have noticed. Sort of in the same vein, should I pan some instruments more? Thoughts/suggestions on what could or shouldn't be panned?
EDIT: New version can be found here.
