I have only one complaint...
I don't think this belongs in Ambiance...It seems a little too "peppy" for Ambiance, since normally that category is used for things that are relaxing and meditative. More or less background music. However, other than that, I think this track is amazing! It sounds like you put a lot of effort into it and, while it seems like it could be Ambiance if you made it sound less "skippy" on one of the specific sounds, imo it currently sounds like it should be under Trance. I do like it a lot, it definitely is something I'll be listening to for a long time, but I just felt I had to put in my two cents.
Oh, and I love the style of this! ^.=.^
