Not bad at all.
The reason I gave originality a low score is because you didn't write this song and aren't the first person to cover/remix it.
I like the melodies, but it feels like the song never really goes anywhere. I have problems with buildup and anticipation as well, and it just leaves the listener disappointed.
In my opinion, the lead should have been louder for a more dramatic effect, because that's where the real emotion is.
Overall a nice piece here, but with a little more work and change (dynamics, etc.), it could be awesome.
