Now I wouldn't stop them, but looking at the results in CSP I am totally underwhelmed by their feature. The inferred geometry and thus shading just doesn't look good to me. Maybe it's the particular example of the girl's head. But the last image (interior) looks even worse, or rather wrong, with gradients all over the place that just don't belong there. I guess to make this work better the app could make use of ai models that better predict the actual geometry, and so can apply shading that is ... realistic, or rather convincing. This would, of course, defy the purpose of a drawing app and take away the fun of painting, illustrating and creating stylized images
