Moving composition while retaining the ambience! I created these categories in this way specifically to capture that.
I.e. making adequate ambient music is doable... but making it stand out while also being appropriate at ambience is hard.
I think the mix is still a little midi on some of the stringed instruments. The effects are also maybe a little narrow in space, like it's kind of panned center. I've been using DearVR micro for placement so I don't have to do all the math on delay between ears and volume of each ear. It works really well for that. It has a bit of extra algo to do spatializing as your ears would reflect sound, so that is a mixed bag in terms of how to apply it. But it does that part really well.
Nice job once again! :)
