I really like this a lot. I am a big fan of John Denver's music and have recently started to learn how to play guitar using my fingers instead of a pick. Something that has really opened my ears to a whole new world where music goes.
Sometimes people post things here wanting advice and critics for their mix, other times they post things wondering how things might be better music writing wise.
As for the mix, you've got it sounding really solid, although I am no expert.
As for your song, I like how you hang on the main background riff, but what in my opinion would really set it off would be if you changed the background chords and took it off into a journey elsewhere rather than hanging on the same somber thing over and over. And I mean that comment in a good way so please don't take it any other way.
Enjoyed hearing this either way very much!!!! Thanks for sharing!!!!!!!!!!!!!!
