I like this one for the contrast the positioning of the figure, and the placement of the color.
It lacks a human touch though. The shadows that exist look like they were created with a filter resulting in odd shaped shadows that fail to portray the objects and textures properly. For example look at the shadow shapes on the back of the head and neck if you were looking at a model and drawing these shapes by hand, you would never represent hair as those shapes. Use a shape or stroke that describes the shape or texture of hair. same with the highlights on the shoulder you would never draw them that shape, that's the result of the filter. Shadow on the back of the elbow, shadows in the hand and knuckles, highlights on the t-shirt these should all be re-interpreted though your hand. Making this change will add detail and present your art more skillfully. Personally I would switch out the white for a tan or brown with some texture in it. Look at OBEY stuff for a good example of this. For representing textures like hair and muscle in solid black though shape alone, study Frank Miller and Mike Mignola.
