yeah I would double check the proportions and measurements with a ruler. The legs do appear too short and the hips too wide from. The middle one the neck also appears too long and the arms too short. It might help to hold them up to an image of a skeleton on a piece of paper or a person on a computer screen just to double check those proportions as you're going. They look well built though so I think if you can just make those adjustments they should work great. I could also see these proportions possibly working for small children though I'd have to double check that as well. Keep it up!
