I placed thin slices of my canes on the horse, roughly following my first sketch. The colors turned out fine against the black background. The small dimples you see in some places come from the tool I used for placing the cane slices.
This is a very fun part of the work, as you see fast results. If something doesn’t come out as I want it to, the slice of the cane is still easy to remove from the horse as I have not pressed it into the soft black clay yet.
