Outer Space: You have created a very rich space sound with those lush pads. I really like the simplicity of the core identity of this track with the minor third drop. There is no complexity, and irrespective of this it feels very complete. Nice job!
Lifefull Planet: The melody line from the A section has a vivid and “green” feel to it which does a really nice job representing the “lifefull” quality of the planet. I think the harmony of moving from a minor chord to a major chord also gives it an upward and optimistic feel that enhances this life-like atmosphere. The B melody on the piano felt like maybe it could have been moved backward in the mix a little to soften the intensity of the key hits, but I don’t think this detracts from the beauty of this piece.
Both of these tracks create a beautiful ambience for the two environments you describe. I would really enjoy exploring in a game with these two tracks playing. Good work on these and thank you for sharing!
