So sexy i dont know who to choose.

I don't have anything against your upload but I must point it out; the faces all horrible traces of Tomose Shunsaku's works and this supposed "artist" does the same for the bodies, I. E.

Compare that to image 27.

Base +16, Meowmux +8, Ayato1941 +2

it common for artist to use other art frame to make his own, sometime they collab sometime they dont, but they hardly say you cant have this pose or design.

you say this could be the same body for 27, it could be, it could be not or it could be some else before that image.

I see oreimo having more than 4 artists work on a same scene independently and they really resemble each other but they all have their owns touch, maybe the colour, the pencil,etc.(i dont know what pics but on pixiv)

All this IMO if im wrong ...well .If you want detail you could find out on his website :)
