I like it! The pad in the mid section of the song sounds more like a house instrument then something for ambience, however i dont know how anyone could mistake it for "futuristic techno funk" or even techno, seeing as ambience is a subgenre of techno, and seeing as you labeled it ambience. dot dot dot... anyway, I do like it and you should make something like it using some varied drum beats, thats really the only thing I can think of to make it sound better. 5/5 from me
