This one was created with Derwent Coloursoft pencils, not my usual Prismacolor. The good thing is that these pencils are really, really soft and blend together easily. The bad thing is that in just a few layers it becomes impossible to add more color. The next stroke tries to lift off what’s already on the surface. This is not such a big deal with lighter colors, but getting good darks with Derwent on canvas (at least on a digital one that was used for this piece) turned into a challenge. The solution: use a softest graphite pencil you have. Koh-I-Noor Hardtmuth 7B worked quite well for me.
