Lovely sounds! I really love the part at 0:32. I like the part less at 0:51, as this Rock-ish vibe is a bit too much for me, but it does fit the concept well. The (what I envision are) sweeping synths give a hollow and hopeless vibe, and the electric guitar fits the electric feel. I also like the ending at 4:04 where only the guitar is left. Nice song :D
