I am the first!
My first shot was like 5+ minutes (did not keep the recording 
). Then I practiced a few time, managed to make this pose under 1 minute!
The big breakthrough is that I learned to pose his upper body and arms at the same time by dragging his head and bend both of them 90 degrees. Then use “Rotate” to adjsut the overall angle.

Lots of interesting poses in there!
