I have to agree with the critique, but for somewhat of a different reason. Anatomically on her left side, the direction she is looking there is two indentations for the rib cage. I get that the first hump is supposed to be her lats, but the only thing about that is only the top part of anyones lats are visible from front angles so that area should be a lot shorter while the second hump (rib cage) should be longer. Her waist should be a bit wider for the style your conveying also. My only other gripe would be that if I drew a skeleton underneath I don't think her humerus, acromion , clavicle, and scapula don't seem like they would be joined, they are a bit to wide, or to far apart. The fingers seem a bit stiff to, her thumb should be pointed out and not bent, so should her other fingers. Hope I am not speaking to harshly, just want to help! (since I can't give official critiques)
