I'm going to say what I've said a bunch of time's when it comes to animations in AVN's.
It's very rarely worth it.
Why? Because it takes a lot of time. It takes a lot of skill. It takes a lot of funds (equipment, or in this case, helpers)
That 30 second promo/teaser (assuming it's 24fps) is the equivalent of 720 normal renders. Add in the other animations, and he's done several thousand "renders" for these animations. Those animations are literally, from a rendering perspective, equal to an entire regular update or 2 or 3.
Time not well spent, even if they're not bad animations by any means. They have nice composition and an artistic feel, like LP's renders do, but the actual sexual aspect isn't anything to write home about. Much less interesting than LP's narration/renders during the sexual encounters. Like the Nat massage or the bikini show or even the hot-tub kiss.
Sometimes animation makes games better, sometimes they make them worse, and in this case it doesn't do much of anything.
If people want animations, go watch animation videos, leave VN's to text and renders.
