Nice! I still have not tried the perpetual journaling part. It feels slightly daunting. I appreciated how Rosalie Haizlett shared at Wild Wonder her experience of starting one and then not finishing and then judging herself when she couldn't keep it up and then eventually finding balance with it.
I did this with the staff at an environmental education center I used to work at. A thing that helped - we used a lined paper journal. It made it easier for folks to begin - less pressure to draw. Though some did draw.
