Guys,why are you even requesting that guy "whoeven" to stop posting his *artworks*?Let him do so.

If you are feeling disturbed or sick by seeing his pics,then just imagine him to be a guy who has badly failed in his human anatomy drawing works and is thus,trying to gain popularity by posting his *artworks* here.That's it.I bet you won't feel that bad after thinking in this way...^_^

(P.S. i know this question is gonna get bombarded with his *artworks*,but it will be him    who will make fun of himself by posting his pic in this post)
