Well, I would work on the tone of the guitar, it sounds a bit tinny in places. Second, maybe work a bit on panning each track so you don't have everything so condensed together, but more spread out for a fuller sound. I like the over piece but it needs a bit more attention here and there. Lots of nice textures going on but would be nice to hear each instrument clearly in the mix. The volume levels seem to be alright, but ones you get everything in a good separation point, then you can further work on any other required mixing of the over all sound.
Peace and Blessings, John
