Gave my new Faber Castell water-soluble graphite pencils a try. I like how easily they blend with water, but need to experiment with them on actual watercolor paper. I'm wondering how much of the line-art I can get to stay  or if I need to couple them with non-water-soluble graphite pencils or actual inking for detail. 365 Sketch 2015: Meditation
