Wow! I have not seen this artist's work before, and it has almost shocked me. The pictures stay very far that we could label them as cute: they are realistic, grimdark and a little gothic. Not the kind of art we usually find here.
The artist is Jean Michel Nicollet , and there are some other works of him here in E-H inside some "Heavy Metal" magazines : /?f_cats=0&f_search=Nicollet
"Néo" is just the french "nom de collection" of the publisher's editorial collection. The uploader must have confused it for the author's surname.
