@smceccarelli This is actually really sound advice! I even have some water-soluble pencils that I've never used haha. I forgot they were soluble. I do layout before I leave any harsh lines, I stipple an outline for the linework, then I do the same thing for the shadows.
Heinrich Kley is Awesome!! He has so much rhythm throughout his drawings. The poses of his characters are expressive and lifelike as well. Thank you for the reference
