i did my take on these little paw things ive seen other ppl do and i'd kinda be down to make it a comm option but idk if anyone would be rlly interested! They'd be like. 10$-15$ ? basically depending on if im just coloring in the lineart or drawing more assets like i did for my fursona as an example lol, also if the paws are symmetrical or not etc, but basically they wouldn't go any higher than 15$ 

Also could make it a base but animation bases r kinda annoying to prepare and probably not too easy to use so. not sure if its worth the trouble
