Albion Tundra and Adagietto really does make for such a expressive combo!
The overall production, resulting atmosphere, design choices and the approach to composition that you've done throughout all of the tracks is to a level I'd certainly consider Professional for sure. You could drop any of the tracks into a large budget open-world game or as piece to play over documentaries and it will work. Not much else to say, great job overall ;)
I'll buy it when I can. Been recently stung for money having to replace a few things breaking on me haha
