Um, I think like 3 out of 10 because his back isn't straight and his elbows Pretty sure those aren't fully right But his back is not straight. I don't look straight at least. Might have scoliosis probably. I don't know.
His hips keep touching the ground which they shouldn't. He should be completely parallel to the ground. His back should be straight and his chest and shoulder should be doing all the work. but he seems like he's dropping his hips before he lifts himself up.
