Paint on feather: Night Storm

I decided to try to draw on feather. I thought that was not easy, because the paint on the pen fell ill, despite the fact that I painted with acrylic.
But I like the result! This is a feather I found in the woods, it is a large, black and strong. I think it's a feather crow.
Feather 32.5 cm by 5 cm
Wolves 18 cm to 5 cm
