In short poses – twenty minutes or less, you will have to use judgement on what details you want to draw. Getting the gesture is of utmost importance. For poses ten minutes and longer, it’s unrealistic to expect dramatic ‘movement’ in gesture of the model. I chose lighting on the model’s back in this particular ten minute pose. Head drawing takes the longest followed by hands and feet. I avoided hands. A profile head drawing takes less time – one only has half the face to draw. The drawing shows quick strokes for some of the shadow areas. Core shadows, the dark strokes that define surface (skin) turning away from light, are fairly predominant. Drawing muscular bodies or overweight bodies is relatively easy compared to drawing skinny people. Probably lack of surface details on thinner torso. One will have to focus mostly on bone structure on such people.
