Lol, sounds tops awesome. You got room for some pads and instruments though. String ensembles, violins, soft airy synths, choir, sine waves... sky is the limit. Drums could benefit from some new layers. You can get nice and fat sounds by layering new samples on top of your others. All of my tracks have 3-4 snare drums that layer to make a new snare drum. You can use the drums interchangeably, solo one for an intro or break down, bend pitches for funzies...
I'm only tossing ideas in your direction. You got something fresh here and I would love to see your style evolve :D
