I'm biased, but I took a big time during my fittings to ensure that the shoulders weren't too big, as the coat have extended shoulders (2cm on each side).
What I believe you're seeing is the right side (the left in the photo), which is not a good indication as I'm putting my hand in my trouser's pocket resulting the "divots", and a good deal of camera distortion (the area where the shoulder are suffers the most from the iPhone camera distortion). Take a look at the left shoulder (right in the photograph), it falls uninterruptedly, almost making a 90º angle with the sleeves. So, yes, the shoulders are extended, but not too big, and the effect is attenuated in real life.
Also, the whole silhouette is not accurately portrayed in that photograph, it has soft and balanced lines. The following photograph portraits the silhouette in a more accurate way.
