I only used pencil lead for this one.
H2 lead to B6 for darker areas like the inside of the mouths facing back the sun light.
Creating shadows for realism and shape. They are key to make pencil lead drawings realistic and intresting to look at.

There's also a significant depth, with 3 plans making a landscape.
1st: Closest Stone shape
2nd: Farest Stone
3th: The orizon

My inspiration came for Zdzisław Beksiński's painting [IMAGE: https://steemitimages.com/DQmeDWtKuNq9GVsE5B2LGo9QsxqTzEDa8tmd8APCX1P4pgD/3d3de5ffc44bd28fe0d2478793a5ea3d.jpg]

And also form Black Sun Empire, a Drum&Bass band from Utrecht / Netherlands
Thier Stone Faces track from 2004
