Don’t be intimidated by reclining poses. Because most of the limbs are not foreshortened, they generally present the same amount of difficulty as standing poses. They’re just turned on their sides.
As with standing poses, use the divisions of the upper and lower body to find the positions of the major joints. You will need to draw your upper bracket on a curve to represent the flexion of the model’s upper body and head. Take note of the perspective at play: We see the model from the back (not just the side) view.
The bend of the model’s left leg will provide some helpful negative spaces and a visually interesting outline.
