I never consider anatomy when I draw stuff Mlai. I just draw stuff. The picture above was drawn based on several things, the pose is taken from two werewolf toys I found and posed like that. I liked the long shape of ones hands, but his face and body was kinda odd looking. So I found another werewolf action figure that was more animal like. The one I was basing the pose from was of the original Wolf Man universal movie, or was very similar to him. I also wanted him to have a bit of that akwerd perspective and posing that I put in everything. Thats why his legs are hinged backwards.
Heres a bunch of things that I did while I was first designing my werewolf. Possible spoiler for the werewolf comic in here. Similar designs may appear on other characters in Werewolf or even penis. I had attempted to save some of my creative process that I do in flash. I'd sketched out some drawings and notes about my Werewolf story, which at the time was only going to be four pages. Now that its a spin off, I'm especially glad I captured some of the things I tried with my Werewolf. Most of it looks disjointed and fragments of ideas are there. The legs I got where I wanted right off the bat. The arms I had tried several things with, one of which I was enthusiastic about but for my main character he needed hands in case he needed to grapple something. Even though he's not shown physically gripping or holding anything, I wanted it to be implied that he could.
Heres the final main art template that I use for most all of his appearances.
His pants contain shading that looks similar to urine, for comedic purposes. Another drawing I did a few months ago had shading that some said looked like pee. So as a joke, he has pee pants shading too.
