Coarse woody debris is a fascinating world for itself. There is a special program applied in the managed public forest around my home to leave more woody debris in the forests. The intention is to improve the living conditions for natural enemies of forest pests. As a result there are many old tree trunks left either standing or fallen. Another great micro habitat are the old tree stumps, covered with moss, dotted with mushroom spawn and little ants and bugs living inside.
I did two versions of the old tree stump. While the first layer of gouache colours dried slowly I did a quick reed pen drawing in ink, which I coloured on the second session.
