I decided to do something easy first like bfdi very simple
Here's how I did it. Ok so first grab a png/reference image of what you want to draw, second paste that into scratch third make the shape of what it is, fourth use the eyedropper tool to get the colour of the dark part of the image and then use the bucket tool to colour in your shape, fifth make a copy of the shape and make it slightly tinier and place it on the top right corner if your shape, sixth now colour in the tiny shape a slightly darker variant of the colour, now just draw oval eyes and hands and legs. A face too and boom your done
