Mm balinese gamelan is really unique. u should go check out javanese gamelan. it has a slower, more meditative ambience and is really interesting too. anyway your piece sounds more like a study of balinese gamelan using the piano as a medium. It's got loads of potential, so dont just stop at copying the gamelan techniques into the piano (though i must say u did a pretty good job with that), but combine aspects of both in ways nobody has thought of. you're the composer. it's your call how u want to go about doing it. :D all the best. and yeah. the links above are really good. :P
