I think it helps to understand what the PRB's aim was...and that was, as the name implies, a return to a more medieval to proto-Renaissance style, and to get away from the academic, stylized, contrived compositions of the high Renaissance (hence, "Pre-Raphael"). In that light, the PRB's stuff can hardly be said to be any more 'weird' than say Van Der Weydn's stuff from the early 1400's..
...or countless other examples I could cite..
That lady doesn’t have a sock-me-in-the-jaw, but the arrangement to show the forehead is typical of what we see in pictures of the time. Whether it’s realistic, or an art style of the day, we have no way to know.
I understand about challenging previous conventions. However, the faces Rosetti painted are very unusual. I’m sure such exist in real life; his choice to paint them shows his personal taste. I think their jaws are weird.
But anyhow, Q.E.D.
And if you're going to argue that Burne-Jones wasn't "really" a member of the P.R.B., just consider "The Lady of Shalott" instead.
