thanks for the replies.
I'm going to put a floor into the scene.
@Scott-Livingston: Yes, you're right with the right feet, it looks unnatural. But I had not only to break the twisting limit at this joint here.
At a few here and there I had to set the limits of rotation higher, especially at the joints of hands, thighs and abdomens/waists.
Try this position yourself, I tried. I fall, but with training you can twist your shin and foot like that.
The gods finger looks awesome, you'd do that, too. Perhaps this distinguish a god...
I'd love to see shadow and reflection like you, too. But to establish that the best would to render it in one part, not in three parts as I did. My amount of memory won't let me render a scene with 14 models. I already ran out of memory with rendering the parts in the back, each one with 6 models.
But one day I'll return to synchrony in motion with more RAM
Addendum: I did a pseudo shadow on a wooden floor.
