I love the chord structure of this - it just doesn't get old. The drums and guitar are extremely well done, too... btw, where did you get the patches for those? I've had a lot of trouble getting a decent guitar patch, as well as a drum kit patch that sounds so much like an actual acoustic kit.
Some tips, though:
I like the effect you applied on the strings - you know, the one that slowly brings the notes from flat to the correct pitch (something of a portamento, but always starting flat)... It's a bit much, however. It takes too long for the correct pitch to settle, and although it does leave you with the desired dissonant effect, it sounds gross. See if you can get the pitches to settle just a bit faster, and it'll sound so many times better as a result.
My other comment is on the voice - it doesn't work. I'm sorry, but as soon as the voice cuts into the song, it's like it suddenly becomes a parody of itself. I understand that the song needs that melody to keep going, but the voice just sounds straight up bad. I would consider giving that melody to an instrument - Something synthetic would work well, I think... You don't want to stray too far from the way the voice is already set up, but it really has to blend with the music a little better than the voice does at the current moment.
Other than that, the loop is really smooth, chords are well placed, the flow is great, levels and mastering are perfect... And as soon as the issues I mentioned above were to be fixed - this would be on my favs list for sure.
9/10, 5/5 - Excellent work.
Power to you, Arnas!
