Creating the 2nd part "Bellows" from the cycle "Organ ABC"

Before I go to continue painting Pinky and Spiky cabin walls, I wanted to created the 2nd piece from my cycle "Organ ABC". It's called "Bellows". I thought it's a good title for the 2nd part because every organ needs bellows and this word starts from the letter B.
​
Bellows serve as lungs of the pipe organ so to illustrate this I first created long chords in my hand parts, then added the pedal part. Without good lungs, one cannot sing long notes, right? Then I cleaned up the score so it would be ready for performance. You can see the process in this video:
