I love this loop quite a bit. Very well sounding all around. My problem with it is your chosing of notes for the second riff. You should change the last 4 notes to fit the melody a little better...It just kind of fades into an abstract sound toward the last seconds when it could ring just as cool sounding as the first set of notes...if you can make those last few notes shine like the first, I for one could use this song in a project.
If not..well it's still a really good song, I gave you a 4/5!
