Feels incredibly too orchestral for an ambience jam in my opinion. The bass notes running through feel a bit stiff and lacking dynamics. The instrument choice isn't bad at all, BBC Orchestra is a fantastic suite, but I wouldn't use it exclusively composing ambience. There's a strong lack of ambient traits here, very little atmosphere, texture, or grain. It just sounds like a (rather nice) orchestral piece. Also the one bass note at the end sort of just retriggers out of nowhere it seems.
