I don't usually let the cat out of the bag as I've been know to abandon ideas if I'm unhappy.
But this time I think I'm good to go.
Working these things through, the image, the materials and the process take up a lot of time and effort....and sleep. Though going for a walk helps as well.
The image is from Rackham, early 1900's
I think it will work here very well.
Cartooning the faces will be done as thread painting and the rest of the body (tree) will be yarn.
