If I ever tried a second shot at adoptables, I would never use any bases, though there is the possible possible possible chance I may use a body outline/frame twice in total if it came to that. Once for the first character and maybe once a couple weeks/months down the line... but that's it. If I were to release an image with, say, five adoptable characters on it, all five of them would have completely unique images, posture, proportion and all. And then if I did five more, those five would also have completely unique structures. As time went on, I might mix and match a couple old ones among new ones, like I said, but it would really depend on if I was super needy about getting them out there. To me, reusing such a thing repeatedly is painful. I could never get myself to do it on a common basis. Not really my thing.
