Why is this so popular ? I mean...it IS very sexy but her face looks horrible.
Well, uh, because it is very sexy for sure. Also, the overall shading and colors are very beautiful. The face is defintely misfortunate though. Hopefully Shinooji will do a revision and fix it in the future.
The eyes are a bit off, perspective on them is wrong and so is the distance between them, also, the mouth and nose are just 2 lines i guess... yeah it's not really good.
