I'm digging it!
The beginning reminds me of the very first steps I took when I played Skyrim for the first time. If this kind of music wasn't playing in-game, it was playing in my head. But then I took an arrow to the.. never mind, I won't dare go there. XD
You definitely captured the aspect of immersion in this one, which admittedly can be hard to do at times. But you pulled it off very well. The sense of being immersed by just audio itself can be pretty powerful, so use your potential to the fullest, and definitely make more like it!
Good work overall! All 5 from me, this was beautiful.
