Girls who take cosplay photos are clearly stratified by "levels", even though they rarely say it openly, and audiences seldom discuss it. In the end, the market distinguishes them through pricing.
Top tier: Natural beauties who are genuinely stunning. They hardly get any plastic surgery, or only very minimal work. They also maintain extremely strict control over their figures. These girls almost never make cosplay their main job. They are almost always actresses, dancers, print models, or even singers who develop in multiple directions. (E.g. Kanna Hashimoto)
Second tier: Pretty girls with minor plastic surgery. They usually lack strong talent in acting, performance, singing. Most of them work as print models. A small number do cosplay, such as Eneko. They almost never show their private parts, and even their early borderline teasing content is very limited. Doing full nudity would only lower their value.
Third tier: Average-looking girls who have undergone major plastic surgery transformations. These are usually the top-tier nude cosplay, and cosplay AV. Due to the financial pressure of heavy plastic surgery. They tend to be very bold in exposing themselves and do hard core in AV, sometimes even showing everything (three holes wide open etc..). They usually earn a lot and then reinvest most of it into more surgery. Many fall into an anxious cycle of plastic surgery addiction. (E.g. Komachi)
Fourth tier: Average girls with only minor or no plastic surgery. They have no advantage in face or figure. If they need to make money through cosplay, their only options are full nudity or outright cosplay sex videos. These are the most common face blurred / censored nude cosplay you will see. To further increase their income, the only path left is hardcore content: things other girls refuse to do, such as anal plugs, deepthroat, nipple piercings, etc. (The Coser of this post is a good example. She do nudity and anal plug together)
Lowest tier: Girls who have nothing going for them and are desperately short of money. Besides catering to very niche fetishes like heavy censoring/mosaics combined with extreme scat play, basically no one watches them. (I can't find a example here in e-hentai, they are just too bad. you may find some from twitter)
