Just a difference in focal lengths of the camera used. The first 2 photos were likely taken at a distance of several feet with the rear camera on a smartphone, which is ideal for photographing people and a better representation.

The last 2 photos appear to be selfies taken with the front facing camera on a smartphone. This is a wide angle lens which causes distortion such as making the face appear more narrow when captured from such a close distance. For real this is some incredibly low iq shit if that guy actually convinced himself his skull shrunk because he doesn't know how cameras work.
