This is a decent loop.
I'm so happy that all the rest of your audio is under a minute. =P It won't take long to review these at all. :D This is a pretty decent loop. I think for it to be used in a flash submission it would have to be about 5 to 10 seconds longer with just a little bit of variety so it didn't get too repetitive. Perhaps it wouldn't be a bad flash to use on a menu or something like that.
