I'm just shocked that he drew an actual smoking hot girl rather than a relatively plain standard looking anime girl. Not that I don't think the other dbz girls are hot
Broken spine and bad hip:waist ratio in the left picture. Grotesquely thick thighs, bad hip:waist ratio, and bad foreshortening on the legs in the right picture.
Broken Spine: You can project the gradual rotation of her torso by tracing the center-line of her clothing as it turns with her body. Seems more like twisted torso material here rather than an actual broken spine.
Bad hip:waist ratio: Taking a look at the wide hips tag and counting the pose, posture and perspective at play, this does not appear to be an horrifically disproportionate. This drawing is not any where close to the artist's upper levels of anatomical exaggeration as well.
Bad foreshortening: Closest approximations of this pose I can find are this and this. We can see comparable locations and visibility of the thighs, knees and shins. If I were looking straight on at a thick girl while she sat like that, this drawing looks plausible.
