I tried very hard to make my mix sound clean and not so muddy, but it appears I have not succeeded. Any tips for me? I'd be grateful. For some reason, I think instruments sound more epic when there is reverb on them. I suppose there is another way that doesn't use reverb? I thought I would make things more interesting by doing variations on the theme (i.e.: changing tonality). The original tune is very short and just repeating the same stuff over and over gets old fast.

Original: I'd be grateful for your feedback on this. I am willing to improve if need be.
