Amen brother...
Just remember - although the amen break was very cool back a little ways - it's now sort of looked at as a cliche - it's ok to use it still, as long as you do something really awesome somewhere else in the track to make up for it...
Just use those breaks as examples - and build off of them to create your own...
This was a really good start - a little monotonous after a bit - bass was plenty fat but needed more variation - and the two basslines that you used didn't feel like they fit as well as they coulda' - Decent rolls and fills here and there though - keep practicing and you'll get it down...
Keep doin' it to it!
