Draw it in a shape of an oval.
Carefully look at the picture and try to repeat a similar arc.
Crocodiles have long and narrow muzzles. If you draw an alligator, keep in mind that its muzzle is flattened and obtuse.
A distinctive feature are the little legs on the sides. We draw only two of them, the other two are not visible in the drawing.
Erase the ennecessary auxiliary lines.
Lengthen the tail
Lengthen the crocodile’s tail to show all its power and strength.
Correct the drawing.
Add the volume
Crocodile is not a small animal, but a predator of an impressive size and its belly is capacious.

If you’ve noticed, the crocodile’s eyes are very small.
Crocodile looks more plausible with teeth in the form of small fangs.
The final stroke has remained – it’s to draw small scaly humps along its huge body.
