There's nothing wrong with Damocles' feedback.
That's the sort of reply that anyone has to bear, if he wants to call himself professional.
Although, I don't fully agree with his points, I can't see anything wrong in the way he did write it.
He said the head is too small and provided a picture where you can see a head shoulder ratio that you can compare to the head shoulder ratio of the model - to me, when I would get such feedback, it is fully sufficient to have a second look at my model to prove whether I think he made a point or whether I still disagree.
