Meany, I would pay just to see what you look like. I've always pictured an evil monster of a girl, so prove me wrong
I like your idea of this not being pornographic, because when I look at ABish stuff, it's not to get my rocks off, though it sometimes happens when it's just ABish-overload. Some minor nudity is fine, such as a diaper change, but when I look at ABDL pictures, it's for the ABDL aspect of it, not to see boobs. Blatant nudity ruins it for me. It's cheap and uncreative.
As for your privacy, why not just blur your face? I know you want your facial expressions to show, but it's better than nothing. Your idea of disguises is good. Any agency or freelance photographer you would work with, I'm sure would have a makeup artist for you.
I didn't know you could draw. I'd love to see your works! I would pay to see them. That might be a good start for your future website too, since you wouldn't need to spend money/time on real-life props, outfits, makeup and photography. You could just put your drawings on your website. Then once you've mastered the website aspect, you could then consider complicating matters by doing real-life modeling.
Whatever you end up doing, it will bring you one step closer to world domination
