So I tried one. I used a photo of a black cup and saucer as a reference. To my surprise, it took about 4-5 minutes and was super easy; maybe too easy.
So i added some complexity. A bronze bust of Abe from the National Portrait Gallery. I'll take you through the progression:
Here is another effort, fruit shapes are not so uniform and the errors are not as obvious.
Try it yourself, it's shamefully easy and you may get a gem out of it!
