I REALLY became aware of that when I was working on my Megan Fox morphs. For real proportion-the eyes were much smaller than V4 stock.

 

Quote - I don't think the eyes need to be enlarged.  There's a recent and annoying trend to make "realistic" faces with overlarge eyes.  They look about right to me, given the human eyeball is around 25mm dia and the human head is approx 5 inches wide.

Definitely needs to lose the tris, though.
