Heh. My biggest feedback to people with trying to write more complex things is to paly an instrument and improvise often.
Composers of the past - musicians of the past in genera - knew more how to improvise, and it was treated as a core skill in music. To me, it's almost like it IS the core skill in music. It's the easiest way to keep practicing dynamically. Focused practice is good when you need to learn something specific and technical. Improvisation is great for developing your musical understanding.
Since you're new at this, I'll say this - you clearly have an ear, even though it is not quite yet developed. You took on something actually pretty ambitious in terms of complexity here, which does take a lot of experience and practice.
I hope this all helps. One of the biggest reasons, and perhaps the biggest reason I host this jam is to help people grow musically into who they are. I want people to come into their own musically, and be able to express the extent of who they are.
Great work, I'm glad you are getting your start here, and I hope getting your start here helps you progress quickly! :)
