Hm. I was more thinking that *I* would spend more time. I'm not sure if more prompts would help that much, less is actually good imo as it's easier to remember and refer to. More movements could definitely work. Maybe even a few different metaphors, or  different biomes? Like an ocean themed one, a jungly one, a desert one etc. so you could pick one that appealed, and on each one the prompts could be slightly different with different art. It would be super fun if you one day made a set of cards - I would definitely pitch in if you ever did a Kickstarter of that. Then it could also double as like an oracle type deck where you pick a card and reflect on it, only through movement!

Another thing that would be cool would be a sample playlist for each prompt that you can access via a couple of different music apps - either hyperlinked for online or QR code linked for a hardcopy. 

Those are my thoughts! Hopefully they might help.
