This is really cool. Could use some very small amounts of compression on the master though. Use the gravity and have the threshold at like -3DB to -10DB - So that the sounds compress, squishing their sounds into each other, making nothing more louder than the other. Some leveling could help as well. The metallic thing that you first hear is 6DB - 11DB too loud. That should be a background element, not an upfront and personal one (with the type of sound it is)
