Well, this certainly was huge - no doubt about that. Mixing was done well, overall. Unfortunately not a lot to work with for a 30 minute epic.
What I mean by that is the four chords over eight bars got repetitive after about five minutes. What's amazing to me is that it lasted five minutes sounding like a Phish vamp (one of their more interesting ones). What starts to happen around the six minute mark is you get tired with the Pentatonic and Major riffs and start making up licks using blues, whole-tone and even some modes (phrygian, locrian) and chromatics I don't think you intended - they just happened. The only problem is that with the same arpeggio for the background, you have to approach them a certain way, then resolve them a certain way for it to work to our 'western-12-tone-ears'. Once that stops working, we hear 'wrong' notes, pick scrapings, clipped and muted strings. What we don't hear is a melody and form.
I definitely give you credit for being so ambitious. And you do have some nice licks here and there. Overall this feels like the lost kind of wandering instead of the leisurely kind.
