they do look similar, but I think the shape of Michaels face would be the same. I see similarities on the top lip, eyes and bridge of the nose.
Michael always had a strong jawline - but people are making out he has had his skull reshaped or something
If you were to photoshop the new pictures of Michael in London from November, and make his skin brown,he wouldnt look that different from the Thriller days - just the nose and chin dimple.
His make up, hair and skin colour, are the only real differences.
