When I saw this birch tree I thought it looked a bit eerie. However, I thought it would be an interesting challenge to draw. I did a crude drawing last year, kept it for a while and was not sure what to do with it. When I had another look, I added a background. I think it brings the tree to life and complete the picture.
The background was created using the gradient tool with multiple points. It depicts the dusk horizon on a clear day in winter.
