Do you listen to RAC very much? It reminded me a lot of them with the arrangement and soundscape choices. I like the direction and with more refining this kind of sound is going to be really nice. I think like the previous comment just overall mixdown could be better to clean it up. Also working with an acapella can be crappy depending on it's original quality, did you pan this one out stereo? I wonder if it would sit better in the middle of the stereo image.
