How the portraits are made
We should be plain about this: the portraits are generated by an image model, not painted by a human artist. You send a photograph, and software trained on centuries of portraiture renders your cat in the Victorian manner, keeping its real colouring, markings and expression. A person reviews the results and runs the studio, but no one sits at an easel.
We say so here, and on the product pages, because you deserve to know what you are buying before you buy it. If you want a portrait painted by a human hand, there are excellent artists who will do that, and you should commission one of them instead.
