Even though this is not improvised. I thought I would post it here since I showed the pencil test here. I actually finished it last fall.
I plan to put this exercise of spontaneous animation into play. I’ve not really focused on it yet, but it’s something I’ve wanted to do.

This rocks! 🙂
Thanks! I spent a fair amount of time on it! I’m ready for another one though. When I think of a new idea! 😀
