Step 6: Draw two small angled lines on the lower left side of the body and close to the neck as guides for the dinosaur's arms.
Step 7: Draw another set of bent lines near the lower right side of the body for the T. rex's legs.
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 T. rex's facial features using the intersecting lines as guides for placement. The eye is basically a small circle with an even smaller shaded circle inside of it to create the pupil. Draw a few lines surrounding the eye to create the cranial structure. A small, shaded slit at the tip of the head serves as the nose.
Step 9: Draw two wavy lines using the horizontal line as a guide to create the Tyrannosaurus rex's open mouth.
