Legolas_hv: Thanks for suggestions. But by now, I'm a little tired of fixing hand and face. I've been doing this for many days, and now is time to go on on my model. Since your suggestions are improvements, not fixes of something wrong, I'll do only if I have time to. I'm already seeing a great headache before me that will be the wings...

Varley: interesting picture. It's another approach in hands, doing blocks first. But to me, it works better copy from photos, or observe my own hand.
