The music is a good start, but since we’re trying to reach people with no DPF background, a voice-over mentioning (very briefly) what’s going on in each step could be a solid foundation for further refinements. fiverr.com has some people who specialize in roughly 30 second professionally recorded voice-overs for $5. Another site I’ve heard of is tenbux or something similar.
Great start! Sounds like you’re making great progress through a rough learning curve.
