when your doing either furries or anthro's they both have different postures in legs, digigrade(I think it was called) and the other I forgot but you can usually notice. one is more straight while the other is more bent in the knees.
tips
>reference canine paws so you can get a better idea of how they look(that helped me .3.)
>For tail placement , its right above the butt crack I think.
>Leg shapes are usually that of a humans , so I reference human autonomy to help place the body parts.
enjoy this sloppiness XD
