I think the mood in this is captured really well. Perhaps it could be a little more dynamic in the beginning, I'm beginning to notice that it seems some of your songs are generally much more interesting in the latter parts because that's when you seem to really get into things and start throwing some mixes in. Not that you necessarily always need to make a song ever-changing, but in congruency with the theme of this particular one I think it would seem more funky if it wasn't so...predictable, I suppose. I can't think of a good word for it at the moment.
Regardless, I think the song is good. It's not really as exciting to me as your other music, but it's done in a different style and I think it's done well in that regard.
