This is the same figure same size rendered with Sennelier Oil Pastels. I didn’t work with the background as much.
When I did the oil pastel (right) I didn’t take the Pastel Pencil version out until I finished. I was shocked how much brighter the oil pastel looked. Soft Pastel should have more intensity than Oil Pastel, because soft pastels have more pure pigment by the nature of the media, but Pastel Pencils are a hard pastel, they need more binders to create the pencil form. Alone though the Pastel Pencil version has great intensity, and the texture’s softness lends itself to flesh, and it was faster because the pencils were easier to handle blending. So, I can see them both for different purposes.
