The screaming crow in more detail. I used water on the drawing and it turned blue/black. That wasn’t the end though, it has now gone brown. Strange. I’ve also had blue fingers for days . They haven’t gone brown. I used a crow feather to draw with dipped in my salvaged ink. It feels like crow blood. The scratchy quality is astonishing. The feather collapses as I apply pressure, but still works and marks are made.
