Drawing Approach

Get a visual plan for placement of focus points or subjects of interests within the picture plain
Make marks for large shape, envelope, to see how top, bottom and sides outer most extremities relate to each other
Divide larger shape into smaller portions, analyzing large proportional relationships
stay away from establishing any particular details or complete outlines.  Instead keep your marks light and soft.  That will allow you to focus on larger relationships of proportions and freedom to change any part as needed.  Use relatively strait lines while blocking in larger shapes, it will allow you to abstract the shapes into simpler, easier to compare shapes and edges.
Use horizontal, vertical and diagonal lines across the shapes to see whether all points of reference line up in your drawing the same way as on a model.  once all large shapes figured out, consider using simple volumetric forms (boxes and cylinders) to double check placement of blocked in outer edges and sizes of all parts.  Planes of forms and inner corners will create clear sense of orientation of all forms in space. 

Use structural lines, like center line, and or skeletal landmarks to block in anatomical structure of the body.
Find for shadow edge and casting shadow to separate light and shadow.  It helps to give unifying tone to all areas of shadow.  It is important not to confuse shadow with dark areas of middle tones(middle light) and local value(the actual value of the object)
At this point you should have a clear map of all shapes and you can focus on mark for outlines and inner corners. 
Sharp light lines should  be used for areas with light value against light background. Contracting dark lines should be used where values will get dark, such as shadow edges.  Make sure to vary softness and hardness of edges.  Core shadow edges will be dark and soft on round surfaces and sharp on sharp corners.  Variation of lines will describe form better than accurate shapes or outlines would.
