I really like this piece
because of it's orignality. I think keeping the guitars acoustic is a nice touch to the song and it brings a really nice feeling with the riff of yours. Only thing I'm wondering is did you use a metronome @ 1:20 and forth? I feel like the song speeds up the tempo just abit. May just be my blind ears that tricks me but I keep on listening and it seems like it's still there. Maybe it's just an artistic touch too...
Well done anyhow, I really like this type of music.
