Greetings Magoruk,
You made a number of very interesting points about this doll. The new TPE head/face does in fact have a noticeable yellow cast compared to the neck and body. DIAOSHI describes the material for the head and breasts as silicone though it is much more likely TPE and probably the same material used for the vagina/anus. These soft, plush materials do leech some oil over time so one had better not lick them. The hands and feet as well as the heads of standard DIAOSHI models are made of another material that DIAOSHI references as TPR which is pliable yet rigid. Of course, since these dolls are meant for intimate contact they should be designed with human health as a top priority. But it’s not a regulated industry.
Why are dolls being made smaller? This doll has a height of 155 cm, approximately 5 ft 2 which is small but not unacceptable. Other models are larger: 158 cm ~ 5 ft 3 in, 165 cm ~ 5 ft 6 in, 168 cm ~ 5 ft 7 in. Smaller dolls means fewer costly materials and more form keeping bodies.
The new TPE breasts can be a little bigger to better match the size of the doll but they seem nicer to my eye than the TPR domes they replace.
DIAOSHI is experimenting and has many other models on offer which is good in the end.
But there is a truly next generation inflatable doll that is still waiting to be born. No company has taken up the challenge yet. This doll would harness the advances in materials and fabrication technology now readily available in the 21st century to fully realize the potential of an inflatable design. Let’s face it: a beautiful 25 to 40 kg (silicone or TPE) doll is not easy to move around and manipulate.

And what about the TPE, which is used more on new models? How do you like it? Did not you afraid of it? This material usually contains some aggressive oil, and thus don't smell pleasant and damages the vinyl. Try to guess what it will do with your face skin after years of sleeping with this doll. In case of damage of TPE part, it is quite difficult to repair. New TPE breasts are very tiny.
Removable head could also be a nice feature. We can have more heads and change them for day, night, playing, sleeping, but it is not very natural. On some photos, it seems that the color of the head is not matched with the body. This could be a disadvantage either, or is it a problem of light when the photo was taken?
Howdy 
No, i am not a Pointer Sisters fan, but hopefully will become fan of this lady as she arrived today finally after waiting about 40 days! In about 7-8 hours, I can present you this super advanced diaoshi lady to you! Cant wait
