^ I agree with that assessment. It is perhaps due to experience and maturity in which she has found better ways to present herself. I also know she has had some work on her face and teeth which have improved her looks and in your photo the make up application is awesome. 
Like fine wine, she improves with time.
Remember when people always used to remark on how many Japanese AV models had snaggle teeth? It got to the stage that I started ignoring people who said it because they were making every model out to be Austin Powers or something...I honestly did not notice when
Hitomi may have had work done on her teeth because I have been completely and utterly entranced by the rest of her body, especially her supernal breasts.
I think the video that really dialed it in for me was the one where she was doing martial arts moves while in a white bikini. Who was this top-heavy Japanese woman able to do this? Seeing her breasts swing around like that, knowing she could take care of herself in a fight too...wowie. I think it was around the same time that
Fuko burst on to the scene. Talk about a one-two punch. Now there were two enormously-breasted Japanese women to perv on?! Well, that when was I completely kn ocked out. I've been worshiping at the altars of both women ever since.
