Lovely track, totally echo the Jamiroquai comment above too, loved the vocals over the solo. Got some Stevie Wonder style vocals in the final minute - fantastic!
Second half of the song would be great if you touched on a little bit of funky disco style elements from 3:24 or 3:46, i.e. some rhythmic open hats between the beats to open it up a bit.
As great as it is, it doesn't 'grab' you as well as it could and a little change up would do it wonders in the middle.
By the way, Don't suppose you know anywhere i can buy paper in bulk around your area, do you?
