Concrete Concerto - Instrumental I wrote last year

http://soundcloud.com/playfan/concrete-concerto

Howdy all,
I wrote and recorded this little piece on Cubase AI4 mid-last year for a film project called Time in Concrete. My Cubase has a limited library so not all instruments (especially guitars) are of the timbre I want them, but I think musically it worked to the film's brief - very atmospheric,rhythmic but still relatively simple and unobtrusive over the picture.
Anyways, let me know what ya think...
