Oh dear- some people draw lines on photos here to demonstrate shoulder angles, but I don't know how to do that. So here's a page with a decent discussion of shoulder angles: http://www.localriding.co...oulder-conformation.html

On that image, look at the orange depiction of the shoulder- the angles are similar to those on Rowdee. A deeper shoulder would have a longer scapula (the top section), and the humorous (the next section) would be more parallel to the ground (a more closed angle). Hope this helps!
