It's really really not best understood as a sophisticated collage tool. You can't take a person and turn them into a cartoon if you're just pasting existing parts of images together. Stable diffusion understands what is a cartoon and it understands what is you (assuming you train it on your face). It spits out watermarks because it understands that watermarks appear in images and it's going to try to reproduce the watermarks if you ask for something that tends to have a watermark in it.
