Step 6: Draw another set of lines on the left side of the body as guides for the arms. Bend the lines to show where the joints will be and draw three smaller lines at the end to indicate the Indominus rex's digits.
Step 7: Draw a couple of lines on the right side as a guide for the Indominus rex's tail. Curve the lines and have them come to a point on the right side. The longer they are, the longer the tail will be.
That's it for the initial sketch! From this point on, press harder with your pencil to get a more defined sketch.
Step 8: Draw the eye inside the Indominus rex's head, on the top left side, as a small football-like shape. Draw a thin slit inside the eye for the pupil. Shade the rest of the eye except for a tiny circle to represent glare. Add a few lines around the eye to indicate the bony structure. The eyes are set deep in the skull. The lines around the eyes create the indentation. Multiple curved lines create the wrinkly texture under the eye. Don't draw the lines too far down the head. They should basically form a circle around the eye. Add the bony brow ridge as a curved line over the eye.
Step 9: Use the initial arcs as guides to draw the teeth lining the Indominus rex's mouth. Draw the teeth as small triangle-like shapes as you follow the path of the arcs. Randomly alternate between big teeth and little teeth. Indominus rex has teeth on the outside of the mouth similar to a crocodile.
