I think this is a very cool loop... I love the background noises. My only suggestion would be to make this loop more progressive, but even so I think you did a very good job with this one. I can just see someone using this in their flash. You obviously are skilled with whatever music program you use. ;)
(I use FL3.56 btw =p)
Please contact me if you would like to use this in a project. We can discuss the details.
