Hey there! The proportions are off, and that's what I believe you feel off. The torso is too long, while the head is too small. The trapezius is too wide and not well-connected to the head. The inner lines you traced do not follow the form of the muscles (the lines you use to suggest the volume, not the scars). Back muscles are quite hard (at least I find them hard haha), so it's great to have references of how the move or look, plus a reference of the pose (you can act the pose yourself, it's always a great idea!) Remember to measure the proportions, and before inking, you can make a previous drawing with a 5H pencil or some soft one. Hope this helps! | Artwod Feedback
