Im gnna keep it real i think the waist is too thin, the abs are way too small (i think??? Since there wiuld probaboy be quite a gap if we calculate where the abdomen/place where lower body starts would be) and also that being said, the belly button is a bit too high but thats due to the abs being way too small compared to the pectorals. Also the distance neck-shoulder isnt equal, and like w ome shoulder being much wider than the other, it also causes the arm to be misplaced. Ummm like when a human faces in that way, a part of their arm is hidden by the torso but if we were to take away the hair and the lower arm the upper arm would be fully visible. But like they didnt do too much of a bad job. Also, i noticed that the collarbones looked kinda misplaced since they are connected to the shoulders (shoulder girdle or whatever, i just know its connected to the shoulders) and seeing how skinny the character is supposed to be, theres supposed to be a little bump right where the collarbones connect to the shoulders. Idk what was going on in the right arm, it doesnt fold like that but yeaaahhh. And the mouth was kinda low. The lineart is definitely not the problem, they added line weight whivh makes it pleasing to look at, the only issues i could find were the anatomical ones and the lack of man nipples LOL i tried to fix it rq but i may be wrong too
