He has too much of a centre heavy face in the after, there's too much volume in the black outline and not enough in the red
That is so nit picky, and it's not even accurate. You really think a surgeon has that much control? Are you picking on his result just to feel better about yourself? It's hard to understand this level of minutia. He looks great after. BUT, photos are unreliable. We'd have to see him in person to truly know.
But again, look at the lighting. In the before, you see no wrinkles under the eye. In the after, you see some. This is a clear indicator (along with the shadows and white balance/pink in the corner) that the after photo is under exposed compared to the other. Under-exposure shows more harsh details. Over-exposure washed out the face. So it's an apples to oranges photographic comparison. You can deduce zero from the images other than his overall bone structure, and especially his muscles around the mouth, look more harmonious after.
