Ehh, it's nice art and traditional metods are always on props for me... but that waist... I dunno, lets other decide, i don't feel like this flagable pic, but bad_anatomy or something like that is quite reasonable here.
Seems "normal" to me as far as animu pics are concerned. That's about how thick the waistline is for most of the girls in One Piece(I mean waist to Hip ratio anyway). Unless we're gonna tag all of One Piece as Bad Anatomy.
