The first piece paints such a wonderful picture for me and creates a great vibe for the theme of this jam. To me it feels how I imagine fog clearing from an environment should feel. I especially liked how the instruments build up on top of each other and still contributed in an interesting way to the piece's idea. The instrumentation itself is soooo fitting for this piece as well!
While I like the idea that you were going for with the second piece, I don't feel the idea was fully developed, in my opinion. The backing chords make sense and are done well, but I'm not sure the off-tempo piano was the best choice for the lead part. I would love to hear an arrangement of this exact piece with some of the acoustic instruments heard in the first piece, with some of those lead lines a little more refined.
I thought the intro for the third piece is soooo good. The acoustic arrangement with the light synth in the background go really well together, and I feel the vibe you were going for is totally there. My only criticism for this piece is that I wish there was more.
Please remember these are only my opinions. Overall, I really enjoyed your submission! I hope someday you'll take some time and really try to flesh out those last two ideas like you did in the first piece, because I think they will benefit greatly from it. Thanks a ton for sharing this! :)
