Okay I've kind of skimmed through the rest of it and there's quiet the amount of possible sounds you could map, I'm not saying you really need to but it could make it flow a bit better at certain places as well as raising the star difficulty a bit more (unless you really don't want to raise it too much, but I'd suggest adding some more of the piano notes as they won't increase the density too much)

Basically, I think you should try and map more of the ignored background sounds like the piano or some drums, I think it would add a bit more to the fairly easy beginning section, I'd also recommend to mixup some patterns here where it gets repetitive, especially around the very dense bits which is around the chorus I believe, I'm not wanting you to completely scrap it but just mix it up here and there a bit to keep it from being too repetitive, over all very impressive map and it looks very fun to play too!
