Most comic artists aren't great at making the faces of their characters distinct, but the way Oliver Queen has been depicted by artists throughout the years is very... particular.
Arrow's Stephen Amell doesn't look like any Green Arrow from the comics spare the New 52 one.
Neal Adams based his Green Arrow off of Robert Redford, but I honestly don't see it.
When drawing Identity Crisis, Rags Morales modeled Ollie after Layne Stayley, which makes more sense than Redford but I don't think he looked rugged enough.
