Step 6: Near the bottom of the body, draw a line similar to the number 7 as a guide for the first arm. Under the neck, draw another short, angled line as a guide for the T. rex's other arm.
Step 7: On the top, right side of the body, draw two long lines that come to a point to form the guide for the T. rex's tail.
That's it for the guides! From this point on, press harder with your pencil for a more defined drawing.
Step 8: Inside the T. rex's head, a little to the right from the middle, draw a small oval-like shape for the eye. Inside the eye, draw a tiny circle off to the side to represent glare. In the middle, draw a dot for the pupil. Draw a couple of curved lines above and below the eye for the eyelids. Draw more short, curved lines under the eye for the folds on the skin.
Step 9: Draw a series of sloping lines above the eye for the big, bony brow. The shape of the brow consists of two sloping lines above the eye to make the shape thick. Add a few extra bumps on the side to give the brow a rougher texture. Add a few more lines between the Tyrannosaurus rex's eye and the brow for extra detail.
