Many thanks for your comments.

One has to make compromises in CG. The walker is 2.10 m in height. Huge but not
impossible. The main problem I saw was the rope and the balance pole. They are
/* very */ much thicker as they should be. But invisible otherwise. And still
the anti-aliasing has problems with them. But increasing the the anti-aliasing
recursion depth yielded problems with the general lighting. So I had to meet a
compromise.

For your suggestion of arse illumination I have to study a little bit more. But
not with this image. I like it, and it will be as it is.

Best regards,
Michael
