Hi! These tracks are extremely commendably, for their well writter piano melodies. Seriously, a lot of other submissions have lot less complicated piano patterns, and rely more on vibes.
I noticed that you often have strings in the background, whenever they get louder, they are really interesting, I think it's a shame that they stay in the background so often.
Also, on the note of orchestration, oftentimes it's advantageous to separate different instruments to their own section on the keyboard. In most cases you don't want two separate instruments playing around the same notes.
Overall incredible job! I hope to see you in next years Jam as well!
