What a level!
It's brilliant to have mixed the saxophone for the cool side and the theremin for the spooky side.
The fact that it's on the left and right reinforces the call-and-answer and I love it.
Now that you've mastered odd time signatures, it's a delight to let yourself be carried along from 4/4 to 5/4 and then 6/4 so smoothly.
Each creation is more accomplished than the last, your progress is remarkable, and I am amazed by the quality of your work.
