I am learning figure drawing on my own (have purchased Proko's figure drawing course but yet to finish). Being the impatient me, I tried to learn some doodling on my own (using Lane Brown's excellent charcoal brushes).. and did a picture recently. However, what I was hoping to achieve was more like the style like Lane Brown or Steve Huston's shading.. i.e. what I see they do is to use some dark core shadow and then lightly (or not much shading) and their figures looks really awesome.. while I had to paint and shade the entire figure for it to even look natural.. how should I simplify the shadow masses and the core shadow.. for example in the picture I painted (with the reference picture attached)? Thank in advance for anyone's advice.
