David ,
After a few listens , I think you are off to a good start 0 to 1:16 ...
This may be of little help to you but I will go over it anyway ...
One thing I like to do for myself is to take a mix of an idea I'm working on and export it as is in it's current state and then place it back into a DAW for an editing chop session

Lengthening sections , time stretching sections ,re arranging things around ,
Changing Keys , Making Majors minors to sevenths ....holding common chord tones while letting the other chord voices and sections move ...
While using my own material as a melodic / harmonic or rhythmic reference track I enjoy taking a section that is lightly instrumented and making up a version w different instruments for a dense orchestra ...or the opposite ...
Taking the fundamental melodic content and repeating it including variations using various octaves while using anything from a solo instrument , duet . quartet up to how ever many tracks I my need to get my idea across..
if it is of any consolation to you I have tons of stuff that I have worked on that are still works in progress ..
It's all good ...
Kenny
