This awesome custom idea of a porcelain doll monster was one of my best designs...but an overly ambitious and unwise execution involving a lot of unstable paint that peeled and wrecked the doll before her debut year of 2023 was finished. (I didn't use a base white doll; I tried to gloss her, the paint got sticky and peeled.)
Today, I know exactly what I'd do better--use all base white parts (Catrine is the sole option for my purposes) and treat yellowing if I have to, dye the spare forearms rather than painting to change their base tone, seal what I do paint, properly, (the safety/equipment for MSC is still an intimidating hurdle to me, though) and maybe source costume parts that are immediately closer to my vision, or sacrifice some visuals to get a design that lasts--I'm okay giving up on the glossy aspect, since porcelain, if not blue china like I aimed for, is often bisque.
While this specific doll was a dud, she was still beautiful while she lived and you can enjoy reading about her here in my original post until such a time as I remake her. Her ideas are all there. The implementation just wasn't right.
