Alligator and crocodile without any shading
I have drawn both an alligator and a crocodile. I drew them very similar but the scales on my alligator are more uniform and the bottom teeth stick out of the crocodile's mouth and overall the crocodile is larger than the alligator.
And this is without any shading or color.
I drew 3 of the 4 legs for the side view because that 4th leg wouldn't be very visible. I also drew webbing on all of the alligator's feet and the back feet of the crocodile.
