bone Landscape drawing

The inspiration for this was ribs and spines made to resemble a landscape.
It is A5 size done with charcoal and pencil.

This is the line drawing with some charcoal put down in the darkest parts.

Started to block in some back ground scenery.

Put in some sky and more details.

To finish I fix some details and textures. This is a small A5 pic because it is more of an idea than a finished piece, I will take some elements from this to use in a bigger picture at some point in the future.
