Step 10: Draw a couple of sloping lines above the eye for Blue's thick, bony brow. The brow should follow the slope of the head shape. At the tip of the muzzle, draw a small slit for the dinosaur's nostril.
Step 11: Lightly sketch a long, horizontal line across the head for the velociraptor's mouth. The line should cut across the middle of the initial arc and toward the left past the eye. When you get the shape and length of the mouth right, darken the line and make it a bit wavy. Darken a bit of the initial arc for the front of the dinosaur's muzzle. Add a few lines above Blue's mouth for detail.
Step 12: Draw another long, horizontal line across the head for the lower part of the open mouth of this Jurassic World dinosaur. This line should slope more than the top line to create the open mouth. Make the line a bit wavy. Darken the lower part of the initial arc to create the lower jaw. The lower jaw shouldn't be too thick. Add a few lines around the open mouth to emphasize the structure. Add a line on the left for the dinosaur's strong jaw.
Step 13: Draw a series of small, triangular shapes that line the top and bottom parts of Blue's mouth for the teeth. The teeth should be angled to the side a bit instead of being straight up and down.
Step 14: Use the remaining lines and shapes as guides to draw the rest of Blue the velociraptor's head. Simply darken the outer edges of the initial shapes to create the shape of the dinosaur's head. Darken a section of the line under the jaw to indicate where the head meets the neck. Draw a series of short lines inside the head for extra detail on the skin. Draw a few more lines between the eyes, nose and mouth to emphasize the muscle and skeletal structure of the velociraptor's head.
