Somehow these dark grey trunks silhouetted against the winter afternoon sky brought to mind tombstones. The field sketch is below using conte crayon, charcoal and white gouache in tinted paper. Above, I tried to darken this with washes mixing burnt sienna with ultramarine or paynes grey, the watercolour scattering on the powdery surface. I have also turned down the exposure on the photo.
Below is the quick preliminary drawing, with the sun behind me. In reality that trunk is tiled with rich brown scales mortared in green. I need to have another try at capturing that.

I’m enjoying these tree renderings. Nice movement and mood.
Thanks. Round where I can cycle to, no mountains, lakes just urban sprawl and bits of woodland. This is a nature reserve where few people go. So trees it is.
Trees are so expressive. It looks like a line of petitioners or perhaps mourners.. . works well with the idea of tombstones (k)
Those are great interpretations, very much in line with what I was thinking, better than tombstones actually. I couldn’t quite grasp the idea I was feeling but it was both sombre and human.
Your descriptive writing is as evocative as your drawings
