Here is a comparison of a male and female werewolf's head
and shoulders. I try to make the male's neck generally
thicker than the female's neck, and I kind of add long
"hair" to the female. You can try adding any hairstyle
you like though, it should work fine.
The female's head is usually more streamlined and less rigid
than the male's. Just as with human females, the
werewolf female should have less detail lines in the facial
area to give a softer look.
The shoulders of the female are also generally closer to the
neck than the male's shoulders. The male's shoulders
are generally broader and have more muscle tone as well.
