One thing that sets this set illustrations (349 Tang Wutong) apart from all other similar ones is adding smiles and receptive expressions. All other illustrators of this illustration type (which there are plenty) only draw serious faces.
I don't know how to call this style, style surely derived from Japanese duojinshi manga, whose top source may be pixiv, although in sure decline against X.
Well, all other illustrators of this kind focus intensively on elaborate and impressive outfits, as well stunning bodies, simply above the already impressive doujinshi manga: girls with giant eyes, extremely lush hair, thin waist, etc.
The women depicted in these new style (which may be Chinese) display much more realistic faces, faces that have a nose and lips, while doujisnhi manga and regular manga quite often only draw a line for a nose. However, the expressions in the new style are always the same: serious, even forced.
When requested to draw smiles or other attractive facial expressions all other authors either object, offer excuses or simply ignore.
Well, at least here author Eric Game was able to draw facial expressions. Thank you.
