It is quite a difficult picture to analyse. Idealy you need one directly from the side.
From what I can see he looks to have a narrow chest but that could be the angle of the photo.
He looks wide behind, Looks to have either a ewe neck or a shark fin neck.
Possiby over at the knee, upright shoulder and long in the back but that could all be the photo.
Sorry but unless there is a better photo of him I realy can't do an accurate critique.
