I love the sliding bass, it adds such great depth to the music. Everything that needs to be said else has been said by SBB. Good job!
It's not much, but damn it has a nice sound. Those delays were used well, though I think you could be a bit more creative with em. Marimba/woodblocks sound great too, really gives it an ethnic feel. I could see so much more to it though, now that you're on it. My imagination could go wild- shakers, congas, other percussion like that- then pan flutes and some more pads- etc. A bit of analog lead synths maybe- some dominant melody could really get it going.
You sure have got something- and as I've said already- I highly suggest you continue on it.
Please contact me if you would like to use this in a project. We can discuss the details.
