Yup. there's not that much difference between them they both have the same amount of strenght and agility.
I love it too my friend, i have an OC character family i made that are werewolf-vampire hybrids they are both bipedal and Quardrupedal in their wolf forms.
I Absolutely adore the anatomy you gave the quadrupedal. It's just enough to see it's sometimes human, but not enough to make it seems freakishly grotesque and overly unnatural.
Now that I look at them, I prefer the quadrupedal werewolf, as it look more carnivorous animal than rabid monster.
only difference is how they move ^^
