So... Here is my second work of art). Still in progress. As for now, I modeled all the objects, did rigging and skinning and some animations as well. Faced some problems: rigging didn't go as I expected. I had bones for both thumbs and palms but rigify addon in Blender didnt create controls for them(. Also as you can see there are some strange tweaks and twists in shoulders and arms - I don't know why. And some weight problems which I couldn't solve. But perhaps it's all about mesh. And of course, the animation doesn't look good at all(. Well, as I mentioned, I'm still working on it. Hope I'll improve in the near future).
