I love the ideas you've got here.
The synths are very soothing and remind me of a lot of beatless ambient tunes along the lines of Autechre.
As far as critiques go, you really need to work on progression.
This track doesn't change up that much and it really bothers me because the sounds used are really fantastic.
Hip Hop is widely known as a very repetitive genre, but if you're going to be making instrumentals you'll need to incorporate changes every 8 bars or so to keep the listener interested, especially when the track you're making turns into a track longer than 3 minutes.
DJ Shadow, DJ Krush, The Avalanches & DJ Food are some good examples of Instrumental Hip Hop to look into.
I highly recommend you listen to a wide array of Instrumental Hip Hop (previously mentioned artists included) to get a feeling of what and what not to do when composing instrumentals.
All that aside though, I really like the Middle Eastern vibe the flute (A sampled one-shot, yes?) gives me.
Keep up the good work man.
