Some really pretty harmonies going on with the melody in the beginning. I can't quite put my finger on it, but it gives it a really tropical and dream-like feel, accentuated by the patch choice and the choice of intervals. The middle section came as a surprise but I love how you've kept the core tone of the track even after switching over to some MIDI guitars. The almost harp-like arpeggios running around here are really pretty, adding this kind of delicate top-layer to the grittier lower end of the mix.
That little interlude section was really cool - that epiano ostinato is great, and having it trade-off to other instruments after a pass or two is a clever way of getting more mileage out of the one melody. The supporting elements here are gorgeous; these added voices do a fantastic job of bolstering the lead lines. You've got a real knack for harmonies.
This was fun to listen to and rather unique, too. Found myself listening back to it another two times just to properly take it all in. Solid work!
