This is partly because the flash has blasted her face with light losing all the shape except for an ugly shadow under her nose. With my Nikon I could try at (very) high ISO for a natural-light shot or use an off-camera flash to shape her face in a more flattering way. But perhaps people used to the very flat / boring light common in mirror selfies won't care about this.
The blur on the edges of the fur look digitally smeared rather than optically blurred.
[edit - okay, I didn't spot that he used off screen light rather than flash. But the effect is similar and hasn't given any pleasing sculpting of the subject. Other processing may have made things worse]
