Martin's hair: a mop of nut-brown hair with a wave to it and hints of curls

Eyes: steel-gray eyes, were often quite blue. They were strong and honest.

Mouth: Had not the full sensuous lips. Sometimes it became stern and harsh. Teeth were white and strong. Ching and jaw were strong and show his aggressiveness.

D) I think the author doesn't like the hero and try to describe Martin by bad characteristics : aggressiveness, eyes without soul
