I loved the concept here, and found it tremendously inspiring how with a simple idea you developed a plausible and relatable world. The details in the description, such as the technical mechanisms of the airships or the materials used to build the minecarts really enrich the experience and made the reader feel transported to your world.
Regarding the music in general, first of all kudos for the naturality you achieved in the recording with a minimal (or none?) usage of quantization. On the other hand, I have some issues with the main instrument chosen, as the piano seems to have a lo-fi quality to its tone, like if it had some high frequencies missing. It might have worked well as a specific voice among others, but used as the exclusive instrument makes the songs feel a bit "muted" and sounding as a very old recording or if playing through a wall, being detrimental to the listening experience and enjoyment of the pieces.
Regarding each track in particular:
Takeoff
- I find this track works great as an introduction. I specially like the usage of silences. It would have benefited from some work on the basslines to accentuate the "floating through the air" vibe, and the percussion hits starting at around 0:45 could be tamed a bit or made into something more "clicky", but I understand you were working only with the piano, so they are more an indication rather than something definitive.
Underneath
- Clearly my favorite track. Some hard dissonances here and plenty of parts with cool harmonic and rhythmic changes. However, it seems to me more fitted for a fight, action or persecution scene, or a boss theme, than for what is described in the player.
A Field of Flowers
- Great development and melodies in this more romantic theme. I can imagine this with an orchestral arrangement working great as a main theme.
Thanks for the great work! The compositions were excellent and with plenty of potential, and I would love to see this world of yours developed further as well.
