I think it´s getting closer to realism. I myself allways evaluate the subD version and tweak there as well as the polyside of it. but in the end I´d say -> a reference pic is very nececcary since you can ask the foto if it is right or not. I can only give intuitiv answers. I use fotos because realism in my opinion is handcraft/science not art.

everything starts and ends in the right place at the right time.
