I like this a lot! I especially like how the harmonies never let you quite 'land' anywhere, it's always a mystery where we're headed, which makes it a lot of fun to listen to. Great job!
On a side note, thanks so much for hosting these challenges, I learned a ton from composing with the monthly challenges and listening to everyone's submissions. It was a great experience, and also the most fun I've had composing in a while. I really appreciate it.
